Re: [Bug: 21.4.14] XEmacs hangs when doing networking

If this is XEmacs hanging, and not the system call failing to timeout, then I would say it's Gnus breakage (inflooping on an operation known to have failed), not XEmacs itself. OTOH, your resolver setup is apparently broken. It is supposed to read resolv.conf on every call AFAIK---changes to resolv.conf should take effect immediately. Anyway, they do for me. One thing you can do is to use a caching nameserver locally. You don't need bind, just something small like pdnsd. Jan> What I don't understand is why the lookup doesn't just Jan> fail. XEmacs shouldn't hang forever, no matter what happens. If Gnus gets into a tight loop, there's not much we can do about it. Maybe we can add some checks for QUIT so at least you can C-g out of it.
