Hi Christian,
Yes, I continue to notice race conditions here and there.  For example,
after doing some basic editing on a HDV project with two stereo audio
tracks and one video track, I wanted to move one audio track down in the
timeline.  When I did this, I triggered a race condition that hung a CPU
at 100% for 30 minutes.  Bummer.  

Hannes gave me some instruction last year on how to track these issues
down using kdbg:

I will try to capture some debug information the next time it happens.
