How would I make a coroutine suspend until an item is not in a set

[marstran]

Encapsulate the set in an actor, and make it send a message to the suspended coroutine when the element is removed.

The coroutine could then suspend by calling receive on the channel.

Long story short I have a set of unique configs I only want one in use at a time, so when I lease it I add it to the set if someone else leases it I want it to block until it unlocks

broadcast which ones get unlocked.. then receive on that and check if it is the one it was waiting for.. broadcast a message that it is locked
you could even make a map of channels.. one for each possible entry

hmmmmm

ActorModel to the rescue!
Be warned though, that API is obsolete.
