Summary: Datagram Socket Timeouts

Initial Comment:
Python 2.4.1, MS Windows 2000 with service packs

I'm trying to have a UDP client check for its server to
start by repeatedly throwing messages at where it's
expected to appear, and then checking for a response. I
set a timeout on the recvfrom, expecting to block for
the timeout and then proceeding to an exception
handler, looping so until data is returned. Instead,
the recvfrom throws an immediate exception "Connection
reset by peer", and I loop rapidly without the
load-softening effect of the timeout (in fact, it's the
same behavior as if I didn't set the timeout at all).
What UDP "connection" is it talking about?

Seems wrong, but is it the implementation or is it me?
If I start the server first, I get one "Invalid
argument" exception in the client. In both cases, once
the server is started, both processes are satisfied.

Thanks.
