I have very very similiar looking code on my harddisk... what inspired you to write this? :)
I have something vaguely similar too; a class that handled a 'pipeline' (?) of Deferreds and didn't allow more than N at a time. My purpose for it was doing several thousand DNS queries and I only wanted at most N outstanding requests at a time, so I wouldn't overload the servers. Ok, so it's not that similar, but it's something that would probably go in the same module ;-)
Actually, it is extremely similar. It's called a semaphore :) This, along with a condition class would probably all make for a good module. I was thinking twisted.python.defertools, if only defer wasn't part of twisted.internet :( Jp
