--- Comment #2 from Vladimir Panteleev <thecybersha...@gmail.com> ---
You are mixing threads with forking. This is a bad idea in any language.

What happens is that a thread from the main process forks, but it doesn't take
along with it the other threads. One of those threads is running the GC, which
holds a lock. As the GC thread is not duplicated during the fork, the lock will
never be freed, thus the forked process will deadlock.
