================================================================
Dear Bug Team!
While using VM, I've been seeing XEmacs exit because it believes that
the last frame on the last console was deleted. This is visibly not
true.:-) Haven't been able to track it down, but today I observed a
new symptom, an apparent infloop while exiting. Here's the backtrace
I got:
Program received signal SIGTSTP, Stopped (user).

After this I got the same backtrace three times at intervals of 5
seconds.

Warning:
Defaulting to the GNU Emacs-derived `sendmail.el' mail client. This facility,
while part of base XEmacs, is heinously underfeatured, and not going to get
better in the medium term. We include it so that bug reports work without
packages; we suggest that you choose and/or install one of the other mail
clients from packages if you're doing something other than M-x
report-xemacs-bug , or even if you are reporting bugs regularly.
To choose a package from those installed, click on "Options" ->
"Internet" -> "Compose Mail With ..." and decide on one from the
list. Gnus and VM are full-featured and have active user communities.
To disable this warning and stick with the old behavior, you can explicitly
initialize `mail-user-agent' to 'sendmail-user-agent .
