Subject: chore(3p/nix): unvendor tvix 0.1

Nothing is using this now, and we'll likely never pick this up again,
but we learned a lot in the process.

Every now and then this breaks in some bizarre way on channel bumps
and it's just a waste of time to maintain that.

-<title>Building and Testing</title>
-
-<para>You can now try to build Hello.  Of course, you could do
-<literal>nix-env -i hello</literal>, but you may not want to install a
-possibly broken package just yet.  The best way to test the package is by
-using the command <command linkend="sec-nix-build">nix-build</command>,
-which builds a Nix expression and creates a symlink named
-<filename>result</filename> in the current directory:
-
-<screen>
-$ nix-build -A hello
-building path `/nix/store/632d2b22514d...-hello-2.1.1'
-hello-2.1.1/
-hello-2.1.1/intl/
-hello-2.1.1/intl/ChangeLog
-<replaceable>...</replaceable>
-
-$ ls -l result
-lrwxrwxrwx ... 2006-09-29 10:43 result -> /nix/store/632d2b22514d...-hello-2.1.1
-
-$ ./result/bin/hello
-Hello, world!</screen>
-
-The <link linkend='opt-attr'><option>-A</option></link> option selects
-the <literal>hello</literal> attribute.  This is faster than using the
-symbolic package name specified by the <literal>name</literal>
-attribute (which also happens to be <literal>hello</literal>) and is
-unambiguous (there can be multiple packages with the symbolic name
-<literal>hello</literal>, but there can be only one attribute in a set
-named <literal>hello</literal>).</para>
-
-<para><command>nix-build</command> registers the
-<filename>./result</filename> symlink as a garbage collection root, so
-unless and until you delete the <filename>./result</filename> symlink,
-the output of the build will be safely kept on your system.  You can
-use <command>nix-build</command>’s <option
-linkend='opt-out-link'>-o</option> switch to give the symlink another
-name.</para>
-
-<para>Nix has transactional semantics.  Once a build finishes
-successfully, Nix makes a note of this in its database: it registers
-that the path denoted by <envar>out</envar> is now
-<quote>valid</quote>.  If you try to build the derivation again, Nix
-will see that the path is already valid and finish immediately.  If a
-build fails, either because it returns a non-zero exit code, because
-Nix or the builder are killed, or because the machine crashes, then
-the output paths will not be registered as valid.  If you try to build
-the derivation again, Nix will remove the output paths if they exist
-(e.g., because the builder died half-way through <literal>make
-install</literal>) and try again.  Note that there is no
-<quote>negative caching</quote>: Nix doesn't remember that a build
-failed, and so a failed build can always be repeated.  This is because
-Nix cannot distinguish between permanent failures (e.g., a compiler
-error due to a syntax error in the source) and transient failures
-(e.g., a disk full condition).</para>
-
-<para>Nix also performs locking.  If you run multiple Nix builds
-simultaneously, and they try to build the same derivation, the first
-Nix instance that gets there will perform the build, while the others
-block (or perform other derivations if available) until the build
-finishes:
-
-<screen>
-$ nix-build -A hello
-waiting for lock on `/nix/store/0h5b7hp8d4hqfrw8igvx97x1xawrjnac-hello-2.1.1x'</screen>
-
-So it is always safe to run multiple instances of Nix in parallel
-(which isn’t the case with, say, <command>make</command>).</para>
-
-<para>If you have a system with multiple CPUs, you may want to have
-Nix build different derivations in parallel (insofar as possible).
-Just pass the option <link linkend='opt-max-jobs'><option>-j
-<replaceable>N</replaceable></option></link>, where
-<replaceable>N</replaceable> is the maximum number of jobs to be run
-in parallel, or set.  Typically this should be the number of
-CPUs.</para>
