Subject: 23.1.50; ido-mode stalls unexpectedly
Date: Mon, 10 May 2010 15:35:25 -0700

BUG: ido-find-file blocks all event processing while listing directory.

therefore, under certain circumstances, emacs APPEARS dead.  actually it
is just waiting while hundreds of subdirectories, on various slow NFS
mounts, are listed (/bin/ls is no faster).  "appears dead" means window
manager suggests killing it, though after directory listing completes
(in 40 seconds), it recovers.

why this matters: it's common to hit backspace one too many times while
looking for files, and in this corporate setting the behaviour is most
unexpected.
