While this does not matter for the signal disposition (libev never
sets signals to C<SIG_IGN>, so handlers will be reset to C<SIG_DFL> on
C<execve>), this matters for the signal mask: many programs do not expect
many signals to be blocked.
certain signals to be blocked.
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.
