Queuing mechanism that is poll/select'able ?

Quoth Chris Ebenezer <chriseb at pobox.com>:
| I'm re-writing some python code to use active objects (i.e multiple
| threads).  I have been looking at using the Queue class as a means to
| send messages between different objects.  
|
| However, the one problem is that since the Queue class isn't based
| around a unix abstraction that is descriptor based, it doesn't support
| select().  Since this is the only mechanism that is relatively
| ubiquitous in unix for the use of polling, this causes problems when
| you try to use Queue's in-conjunction with other 'eventing objects'
| like sockets etc.
|
| I'm pondering writing a Queue-like class based around UNIX domain
| sockets (pipes would be even better but would have built in
| limitations) and cPickle, but before i do this i thought i would ask
| around to see if such a beast already exists.
|
| So, does such a mechanism exist ?

I have had to do a similar kind of thing, though in the context
of BeOS native thread & message handling vs. sockets.  I don't
have an existing implementation that works with Queue, but I hope
you will find that existence of such parallel implementations
supports the concept.  In other words, good idea, go for it!
