mutt and NFS

[Ethan Benson <erbenson@alaska.net>]

I have /home NFS mounted, and i also have mutt configured to watch
various mailboxes that i have procmail dump mail into:

mailboxes ! =in-bugtraq =in-debian-devel =in-debian-user =in-debian-powerpc \
 ....

now when i use mutt on a machine with NFS mounted /home it will say
new mail in in-debian-user for example, i c to that mailbox
read/delete all the mail, hit c again to switch to the next mailbox
with new mail say in-debian-devel read/delete the mail there, now both
mailboxes are empty but mutt says new mail in in-debian-user, so i
change to it its still empty, no messages have been delivered there,
and now mutt is saying new mail in in-debian-devel and so on it will
just go in this loop forever...

if after this has occured i run mutt on the machine with the exported
/home mutt says new mail in in-debian-user but its still empty but
once i change out of the mailbox its fine and no longer erroneously
claims there is mail there.

the mailbox shows and zero length on both machines when mutt is
claiming there is mail when there is not.  

server uses kernel 2.2.14 with knfs, client uses kernel 2.2.15pre3
(with ppc patches) also another client i tested runs 2.2.14, all run
lockd and i have tested that file locking is working properly with a
small C program i found in the BTS (yes i read the long boring saga of
mutt and NFS) 

is there any way to fix this or should i just ssh into the main box
for mail?
