Yep, your terms are correct, with that caveat ("immediate" or "urgent"
without being "real-time"). So you're definitely looking for a
priority queue.

It may be possible to patch a different queue object straight into
Pool, but I've never done anything like that. It's probably best to
dig in the code and add an option somewhere to pass in a queue object
- that'd be a very useful feature imho.
