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.
