+On very high system load, an audio interrupt may occur while the
+audio process is filling audio ring buffers. This triggers bogus
+(and useless) correction code in the 
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=audio&sektion=4">audio(4)</a>
+driver causing the audio application to go out of sync, and in turn causing
+continuous stuttering until the application is restarted.

+will send each synchronization message twice, causing client applications
+to think that buffer underruns are occuring.  Depending on the
+application, this may cause the sound to stutter.
