Hello,
I suggest to look at the implementation of the function "ev_sighandler" again.
http://cvs.schmorp.de/libev/ev.c?revision=1.448&view=markup#l2029
It calls the function "ev_feed_signal" which works with the global array
"signals". I find that the use of this data type is not async-signal-saf

libev is quite obviously not a strictl

I would see it as an "open issue" (or more a bug) for a specific implementation
detail where I would like to recommend a few

Can you elaborate on why not?

If you check the header file, you find that ev_feed_signal_event is
writing to a variable of type EV_ATOMIC_T, which turns out to be a
typedef for sig_atomic_t.
So it's "almost" standards-compliant, except for the fact that
technically the standard says you must use volatile, and libev uses
memory

Actually, "volatile sig_atomic_t", unless overriden.
