Weird... I think it's trying to lock /dev/null ...

Some more information. I used truss and found that post
tries over and over to (apparently) do something
related to locking and (apparently) eventually gives up:

post is running:...

19114: stat("/dev/null.lock", 0xFFBEE058) Err#2 ENOENT

This repeats about 8 times until:

19114: open("/dev/,LCK.cQaqvL", O_RDWR|O_CREAT|O_EXCL, 0600) Err#13 EACCES
19114: stat("/dev/null.lock", 0xFFBEE058) Err#2 ENOENT
19114: access("/afs/cs.uwm.edu/users/csfac/boyland/Mail/MailAliases", 4) = 0
19114: open("/afs/cs.uwm.edu/users/csfac/boyland/Mail/MailAliases", O_RDONLY) = 4
19114: fstat64(4, 0xFFBEED60) = 0
19114: ioctl(4, TCGETA, 0xFFBEECEC) Err#25 ENOTTY
19114: read(4, " j u n i o r : c c h e".., 8192) = 5138

and now it goes off to do its work.
So it looks like it wastes 40 seconds waiting for something
to happen, and then gives up.

I'm trying out nmh 1.1rc3.
I haven't installed a nmh before this level (I had been
using nmh 6.8.3). So far it seems compatible in many
ways but the "post" command takes an annoyingly long time.
Is it timing out on some new action?
