I really don't think that was or is the issue.

I tried adding different sleep delays into my script, which would get
executed just after the umount on each partition/filesystem that was
just backed up.  I tried different small values for the sleep... 1, 2,
3, and finally 4.  The 4 second sleep seems to be adequate so far for
preventing the problem from reocurring.

It's a shame that I had to solve the problem this way, of course.  I would
like to assert that the problem is being caused by either a bug within
the mount command or else possibly in the kernel, but I've learned the
hard way never to do that without absolute proof of any such claim.
I don't have time to develop that just now, so I'll live with 4 second
delays until those prove unworkable.
