Nope.  Turns out it didn't catch all the problems, just some of them.
I still caught some hangs even with this patch applied; and Isaac
applied a race fix that still didn't help.  So, no, it didn't solve

Lots of people apparantly don't see it.  Isaac certainly never has.
But I had one file that exhibited the problem 100% of the time.  I
reduced that to _some_ of the time with a few other changes, but now I
can't reproduce it anymore once the avformatdecoder logic bug was

Granted, there still may be issues burried in there....
