The initial problem was test_3_join_in_forked_from_thread() and the hangs does still happen:

[324/356] test_threading

(neologix's patch doesn't change anything for x86 Ubuntu Shared 3.x buildbot, which is a Linux, not a FreeBSD)

I don't know why it only hangs on this Linux buildbot. It's maybe an old Linux kernel, an old GNU libc version, or something like that?
