* Don't link against pthreads. This was added way back in r211
because Berkeley DB needed it on some platforms, but we don't use BDB anymore. On FreeBSD, if you link against pthreads, then the main thread gets a 2 MB stack which cannot be overriden (it ignores "ulimit -s"): http://www.mail-archive.com/freebsd-hackers@freebsd.org/msg62445.html This is not enough for Nix. For instance, the garbage collector can fail if there is a pathologically deep chain of references (http://hydra.nixos.org/build/556199). 2 MB is also not enough for many Nix expressions. Arguably the garbage collector shouldn't use recursion, because in NixOS unprivileged users can DOS the garbage collector by creating a sufficiently deeply nested chain of references. But getting rid of recursion is a bit harder.
