Subject: watch: set %SIG for non-signalfd/kqueue
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=530db44a85fc48c63b7f97a056f384946753b7ed;p=thirdparty%2Fpublic-inbox.git

watch: set %SIG for non-signalfd/kqueue

We need to ensure there isn't a window where we lose $SIG{CHLD}
handling.  This is the second part in getting t/imapd.t to pass
the reload-after-setting-imap.pollInterval test

That said, I'm not entirely happy with the way -watch jumps
in and out of the event loop.  It's historical baggage from
the pre-event_loop days.
