Hi!
For me, on two different 5.3-stable machines a simple ikectl reload
triggers a loop in the 'iked: ikev2' process. Aborting 'iked: ikev2' a
few times, it usually gets the signal in event_queue_remove() in
event_del().
To reproduce, basically I just start iked (no matter with that
parameters), invoke `ikectl reload`, then after ~2 seconds ikev2 starts
spinning. It doesn't even need an iked.conf, it is just an empty file.
In more detail: I started /sbin/iked -dvv, executed ikectl reload,
waited until "config_getcompile: compilation done" showed up in iked's
terminal, then saw iked's processor use rise up in top(1), then pkill
-ABRT -f ikev2. Now I saved these coredumps under different names:
iked.core-[0-9]+ , then executed gdb in a loop from a shell and got the
bt from every (currently six) coredump [1].
I also recompiled libevent with -DUSE_DEBUG (then recompiled sbin/iked),
and saved iked -dvv's (and libevent's) output on the terminal [2].
Anyone got any idea what could be going on?

Around line #392 one can notice the loop. I've trimmed most of the
redundant lines.
