While programming something using signals, I happened to notice
that Linux resets signal handlers after a signal is caught (i.e.
you have to call the signal function again from within the handler).
Looking at the signal(2) man page, I found that including bsd/signal.h
instead of signal.h fixes this behaviour. How about standardizing
this to POSIX.1 by having Linux stop resetting handlers? The race
condition that could happen if the signal is generated before
the signal function is called again. And besides, doing so won't break
existing Linux programs (since the signal function would simply be
called twice).
So, what about it?
