I'm just about to test your subsequent patch, but just for information,
without it, the event queue underflow also causes a crash in
advance_event.  Hopefully this will go away now.

For anyone testing, you need to make httptimeout as small as possible,
even if not using HTTP, to make these failures likely.

As this is a public list, the confidentiality part of the following
doesn't apply.
