just wanted to comment on this one: this is an event struct that we've
forgot to event_set() for; yet, we tried to event_del() it.

it's fairly common since on openbsd' libevent (ie 1.x) it is safe to
call event_del() on a zero-initialized struct event, while libevent 2.x
that you'll now find commonly everywhere (and also on OpenBSD; just not
in base) it's no longer allowed.

Depending on the compiler optimization this might also turn into a
segfault on libevent 2.0 -- been there, done it.

(currently ENOTIME to search for the cause, just wanted to highlight this
and not have it lost by the chroot part of the issue)


Thanks!
