That was why I posted the workaround for this problem of using touch
to set all of the timestamps to the current time.  I am not sure you
noticed it.

If there are a small enough number of files then it is statistically
likely that this will succeed.  However I acknowledge that if there
are a large number of files that it might take so long to complete
that it would cross a clock tick boundary and cross from one into the
next.  I wouldn't be surprised to hear that it took a run or tree in
order to get the task done all in one time tick.  But I think it very
likely that this would succeed.

Sometimes these systems that are extremely reduced in functionality
just are not worth the effort to support.
