bug#2446: 23.0.90; C-g C-g in sending mail

[Richard M Stallman]

I mistakenly sent a message from `emacs -Q', so `sendmail-send-it'
tried to run the sendmail program, and it hung.  I typed C-g and Emacs said
Waiting for process to die...(type C-g again to kill it instantly)
(which comes from call_process_cleanup).
However, typing C-g again had no effect, and Emacs remained hung
for a long time.  Eventually the process did die and Emacs un-hung.




In GNU Emacs 23.0.90.4 (mipsel-unknown-linux-gnu, GTK+ Version 2.12.11)
 of 2009-02-23 on lemote-yeeloong

'mipsel-unknown-linux-gnu' 'build_alias=mipsel-unknown-linux-gnu'
