I'm running 21.0 "Norwegian" on a Linux 2.0.34 system and using
VM 6.53 for mail.
When I hit "g" to get messages, more often than not, XEmacs hangs
indefinitely, and in my /var/spool/mail directory I have
-rw-rw---- 1 cgw mail 2353 Oct 2 12:28 cgw
-rw-rw-rw- 1 cgw mail 4 Oct 2 12:29 cgw.lock
when I forcibly remove "cgw.lock", XEmacs wakes up again.
