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 ;-)
