To give short feedback on the issue: Doug Rabson sent me a patch (that's
already commited to HEAD). With the patch I didn't observe a panic
within the last 48 hours, so I consider the bug fixed. The MFC to
7-STABLE is scheduled as I could read from the commit log.
Thanx,
Oliver
PS: This is the kind of great support I sometimes wish expensive closed
source software would have, too!
