Btw, recent-ish versions of
http://man7.org/linux/man-pages/man7/signal-safety.7.html
have
* POSIX.1-2003 clarified that if an application calls fork(2) from a
signal handler and any of the fork handlers registered by
pthread_atfork(3) calls a function that is not async-signal-safe,
the behavior is undefined. A future revision of the standard is
likely to remove fork(2) from the list of async-signal-safe
functions.
