Problem with 'mush' and A/UX 2.0

[Mat Davis]

I've just upgraded the machine I use to read mail to A/UX 2.0 and I'm now 
having problems with mush (Mail User's Shell) version 6.5.  Everything works
fine until I try to quit mush and then the process hangs.  I assume that it
must be hung inside the kernel somewhere, because I can't kill it even using
'kill -9' as root, and even shutting the machine down to single-user mode
doesn't kill it.  As a result, if I reboot the machine to get rid of the
process, one of the file systems can't be unmounted and A/UX has to re-check
it.

As long as the process is hung, I also get 'portmapper not responding; giving
up' messages about every ten seconds on the console.  The port mapper *is*
running, and everything else I've thought to check is fine as well.  This
program worked fine under 1.1 and I did try recompiling it, but nothing has
helped.

I've also checked the permissions on the mail file and they're ok.  Even
with a mush process hung and 'fuser /usr/mail/davism' showing that the mush
process is using the mail file, mailx has no problems accessing or updating
the mail file.

If anyone can offer suggestions or help (via e-mail) I'll appreciate it.
