Fix bug with SSL-connection and XMLRPC...

...see my monologue at
http://thread.gmane.org/gmane.comp.bug-tracking.roundup.user/9700

This also fixes a race condition where the forked roundup process would
consume 99% CPU resources after the client opens the SSL connection but
doesn't send anything, e.g.,
 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
 s.connect(('localhost', 443))
 ssl_sock = socket.ssl(s)
