I'm just agitating... but bug 214482 seems to detail that two threads calling vsyslog() lead to a death embrace. I'm just posting to get some wider eyes or opinions on that. In the bug, I've kill -QUIT the mpd5 daemon and looked at it's corpse. I had to kill -QUIT because the daemon is completely unresponsive. Regular kills don't do anything. In the mpd5 binary, there are 3 threads. One is sitting in poll() and the other two are stuck asking for a lock inside the vsyslog() library function.
