I have not seen this before, but I found a range of problems when digging
into this issue.

I could however successfully perform the operation after my fixes were
committed. I chose not to include the patches in this mail, as I believe you
need other multi-interface related patches (done recently) as well to have
this working properly.

Please get the latest sources off the CVS and try!

THANKS for using the interface, for reporting the problem and for providing a
perfect example of how to repeat the problem you were having!

PS, when calling the curl_multi_perform() function within the select(), when
a socket is ready for operation, check the return code! It will return
CURLM_CALL_MULTI_PERFORM in multiple situations, so it might be an idea to
write the code like this:

        while(CURLM_CALL_MULTI_PERFORM ==
              curl_multi_perform(multi_handle, &still_running));

For maximum speed performance. (I know, my example codes don't do this, but
that's because I'm silly person.)
