Hi Micah, Sorry for not replying to this bug report before!
I have experienced similar hangs with mtail in the past, although not as consistently as you describe. Nevertheless, during the many iterations of the 3.0.0 release candidates, there has been lots of improvements and I have not seen these kind of hangs any more lately. If you still have the programs you were using, could you check if this still happens?
Thanks. -- Martina Ferrari (Tina)
