While working on libev support I found the problem we were seeing with
libevent. It is fixed in current svn trunk, which should make unbound
work fine with many libevent versions.
The problem caused threaded race condition problems. Most of the time
this race condition did not cause a problem. It only happened with
libevent (and also libev, which is specifically supports the nonfeature
involved, and crashed for me so I could debug it).
Haw Loeung graciously tested the fix for me, and reports that his
libevent problems seem to be over.
The fix is scheduled for the upcoming 1.1.2 release.
And yes the idea was to support libev to help debug problems with
libevent. I would like to support libev and libevent both as options,
so that people can choose the faster, or less buggy library if needed.
An easy way to use libev, without installing it, is to build libev and
give --with-libevent=/home/user/libev-3.51 to configure for unbound.
