Both KebasData and HTTPMounter use httplib to access the external server, but what happens while that request is handled? Will my Zope thread just be waiting idle, or can it handle other requests?

with KebasData, i use timeoutsocket.py to try and limit the time spent on requests. however, this also affects other zope requests.
i've looked at TimeoutSocket.py from cvs.zope.org. the operative word here is look :P
i havent yet found a good way of tackling this. any info, pointers welcome.
The problem I see is that the timeoutsocket has its own "select" call. So in worst case we wait until the timeout doing nothing. What one would like is to somehow call the poll function in asyncore (The same way the Zope main loop does, so Zope is able to do usefull stuff while we wait). But then, what should the callback be to be able to continue again from the recv statement? (And what happens if we get an exception from something done while we were sleeping...) / Johan
