Don't race when calling event_active/event_add on a running signal event There was previously no lock protecting the signal event's ev_ncalls/ev_pncalls fields, which were accessed by all of event_signal_closure, event_add_internal, event_del_internal, and event_active_nolock. This patch fixes this race by using the current_event_lock in the same way it's used to prevent event_del_internal from touching an event that's currently running.
