You are right loewis.  DST does not have any effect on the wait time.  I haven't looked at this in a while and I shot off a reply too quickly.  The point is that a sleep (or wait) of any sort should not depend on the wall clock.  While I can undertand rejecting this patch, the underlying bug still exists and I hope a solution can be provided.  I plan to look into a better fix myself.  Thanks.
