@ -2132,10 +2132,14 @@ This means that before calling C<exec> (from the child) you should reset
the signal mask to whatever "default" you expect (all clear is a good
choice usually).
In current versions of libev, you can ensure that the signal mask is not
blocking any signals (except temporarily, so thread users watch out) by
specifying the C<EVFLAG_NOSIGNALFD> when creating the event loop. This is
not guaranteed for future versions, however.
The simplest way to ensure that the signal mask is reset in the child is
to install a fork handler with C<pthread_atfork> that resets it. That will
catch fork calls done by libraries (such as the libc) as well.
In current versions of libev, you can also ensure that the signal mask is
not blocking any signals (except temporarily, so thread users watch out)
by specifying the C<EVFLAG_NOSIGNALFD> when creating the event loop. This
