fix(3p/nix): do not call vfork r/1457
The use of vfork() in Nix is entirely illegal. Quote:

If the process created by vfork() returns from the function in which vfork() was
called, or calls any other function before successfully calling _exit() or
one of the exec*() family of functions, the behavior is undefined.

-- Linux man-pages, release 5.05

Add a TODO to use the higher-performance variants of clone() on Linux when it
is available.
