[Message part 2 (message/rfc822, inline)]

From: Leo <sdl.web <at> gmail.com>
To: bug-gnu-emacs <at> gnu.org
Subject: 23.1.94; make-network-process and emacs hangs
Date: Mon, 15 Mar 2010 16:01:20 +0000

The source code of make-network-process (around line 3648 in process.c)
seems to suggest that this function is blocking and my experience can
confirm the case.

When there's no network connection, make-network-process returns in a
short duration. Where it become nasty is in a network where certain
ports are blocked, for example, in my uni's wireless network, the irc
port is blocked and if I accidentally run M-x irc then emacs hangs for
hours.

Could this be improved i.e. by wrapping it in with-local-quit?

Thanks.
