An MHCONTEXT file of /dev/null is a special case.  But, is it the only
one?  There may be other cases where we try to create a dot-lock file
but do not have permissions.  We should insure that we handle that
properly.  Do we try to lock files that are writable in directories that
are not writable?  How do we handle that?

If creation of the dot-lock file fails due to permissions retrying is
not likely to help, we should take a more appropriate action.

Thanks.
