LISTEN/NOTIFY and python

["John D. Burger" <john@xxxxxxxxx>]

Hi -

Does anyone have any suggestions for how to write client python code  
that uses LISTEN?  The only thing I can find is the older PyGreSQL  
module (import pg), which has getnotify(), but this seems to require  
busy-waiting.  Is there any way to do this that will use select() or  
something under the covers, so my client doesn't spin up the cpu?   
(Yes, I know I could poll-sleep-poll-sleep - that's what I'll do if  
there's nothing cleaner.)
