Given this added detail:
The mechanism is essentially a queue. New sets ("work items") are being continuously added asynchronously with the resources (represented by the booleans) becoming available.

This poses another problem, because the "boolmap" structure will grow continuously. If the "sets" queue can grow to the point that the process blows up after a while, then the accumulation of hash keys in the "boolmap" structure is going to have the same effect. You'll need a little more code (and more execution time -- but hopefully not too much) to delete "boolmap" hash keys as the corresponding sets are deleted.

And one more question, which might be unimportant, but the "boolmap" makes it relevant: When adding a new "set" to the queue, what if all the booleans in this set are already true? (Not that I'm curious about that, but it's something the implementation should take into account.)
