WSGI has this ability now - it's yielding an empty string.  Yielding 
an empty string is a hint to the server that the application is not 
ready to send any output, and the server is free to schedule other 
applications next.  And WSGI does not require the application to be 
rescheduled any time soon.

In other words, if saying "don't call me for a while" is the purpose 
of the extension, it is not needed.  As Graham says, the thing that 
would actually be needed is a way to tell the server when to poll the 
app again.
