Dear Bug Team!
I do a lot of ad hoc filtering of HTML files using shell pipelines. I test
those pipelines in XEmacs using shell-command-on-region. With 21.5 I notice
this process has become abysmally slow. I've whittled the problem down as
much as I can. If I visit /usr/share/file/magic (~ 360Kbytes on my Mac) and
execute
C-x h M-| cat RET
the command executes nearly instantaneously, as you'd expect. If, on the
hand, I execute this little Python script instead of cat:
import sys
for line in sys.stdin:
sys.stdout.write(line)
or this even simpler one:
import sys
sys.stdout.write(sys.stdin.read())
the command takes what seems like forever to execute. I just measured it at
about 19 seconds on my Mac PowerBook. I get the same result whether I use
Python 2.3, 2.4 or Python built from the latest CVS source.
I no longer have XEmacs 21.4 installed. If others can't reproduce this, let
me know and I'll download and try it. I don't recall this happening with
that version though. I can also give it a try without any fink (/sw/...)
libraries linked in.

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 .
