I should mention that if I change my code so the workers just pull
things off the job queue but don't put any results on the result queue
until after they see the None sentinel in the job queue and break out of
the loop, I don't get the deadlock. So it's something about getting from
one queue and putting to another queue in close proximity.
Hopefully I'm making a simple mistake with how I'm using the library and
it'll be easy to fix...
Thanks,
Matt
