If this is something we really think we'll be adding back in the
future, is there someway we can conditionalize its use (default off
perhaps) so that if a particular server wanted to take advantage of
it, they could.  This would seem preferable to just backing out the
whole patch.

Another aspect which I didn't consider when we added it is what it
would do to older versions of the servers which didn't have TFSYNCFS
-- maybe this is a good case study for the .L graceful degredation
plan we had talked about in the past where you try a tfsyncfs and if
the server returns an error that it doesn't implement it you back off
to another solution.

Thoughts?  Sorry if I'm being dense -- still adjusting to new sleep
schedule with new baby and spent 16 hours yesterday cranking out two
publication submissions, so folks will have to bear with me for a bit.
