Are you sure about that?  Wouldn't it work something like this:
Suspend the Fiber, perhaps push the request to another IPC thread group that
is farming out the requests.  Then when a reply comes back in, to send it
back over IPC, and then that part would resume that Fiber which was
associated with the request/reply.  

Polling in general seems like a bad idea.

Perhaps I'm answering my own question as to how to do it?
