Do you have a simple test case that reproduces it? If it's our bug we should fix it. > Is there a clean way to block on multiple queues currently in svn ? Not right now. However you may be able to use a loop that includes m0 = msgq0.delete_head_nowait() m1 = msgq1.delete_head_nowait() time.sleep(0.010) or something similar > I saw reference to a message passing interface of some sort upcoming, > but I assume this is not currently available ?
