See below. I've reproduced this once with a current 22 branch CVS
build (Carbon), as well as with 22.1 (with -nw), but can't reproduce
today, so no backtrace.
According to Eric, it appears to still be an issue in Emacs 23
("Emacs.app"), and there seems to be a very long (15 minute) timeout.

Hello,
Does this issue still exist in emacs-23? Can it be reproduced in any
simple manner without access to Matlab? Does it exist on an X11
build of Emacs on Mac OS X?
If I try just
(make-comint "MATLAB EEI" (cons (system-name) 5600))
on Emacs.app on my system, with nothing listening on 5600 (but not a
packet-dropping firewall either), I quickly get a lisp error about
'(file-error "make client process failed" ...'.
thanks,
Adrian
