It's a bug in mush, but it isn't a particularly interesting one. ;-)  The
problem arises because mush does a fork() before sending mail, so you don't
have to wait for the MTA to complete its possibly long-winded task.  After
the fork, both the parent and the child have a lock on the window display,
but the parent wants to do i/o, so it breaks the child's lock.  The child
is never going to do anything with the display, so that's no problem.

Unfortunately, although I'm able to figure out that's what is going on,
I'm not able to figure out what to do about it. :-(  However, the message
can be safely ignored, so I'm not going to worry about it until after the
holidays (and then all I'm going to do is make *Dan* worry about it :-).
