--- Comment #4 from Lennert Buytenhek <buytenh at wantstofly.org>  2012-09-03 19:32:07 ---
This turns out to be (another!) ivykis bug: iv_signal uses a spinlock
to protect its process-wide state, but uses a PTHREAD_PROCESS_PRIVATE
spinlock instead of a PTHREAD_PROCESS_SHARED one, which screws up when
iv_signal's atfork handlers are called, and the child's spinlock ends
up corrupt after the fork().

I have a fix that I'll commit to ivykis HEAD and stable-v0.30 once
you let me know whom to credit the discovery of this issue to.
