@rhettinger I removed "synchronized queues" because they are now described in Concurrent Execution, and it seemed confusing to mention them if they are not listed below.

I see your point about "heap" without "queue" attached to it, though. I can omit the mention to double-ended queues, so it reads "heap queues" again. Or perhaps "heap queues, double-ended queues, ...", but this sounded repetitive to me.

Would that be ok for you?
