[Bug: 21.4.18] open-network-stream freezes and uses lots of CPU

================================================================ Dear Bug Team! (open-network-stream "test" "TEST" "news.inet.fi" "nntp") freezes my xemacs and uses bunch of CPU-cycles (abt 90%). Connection is established in a sence, that using port forwarding script that dumps traffic on a screen I can see the nntp-server sends a valid reply. Xemacs just doesnt seem to react to it in any way. ================================================================ System Info to help track down your bug: --------------------------------------- OS version: Microsoft Windows XP [Version 5.1.2600] OS: Windows_NT XEmacs 21.4.18 "Social Property" configured for `i586-pc-win32'.
