Yes, I'll do it.  Should be much easier than figuring out how to get
explicit JOINs to be automatically reordered by the optimizer.  :-)

The way I see it, the old logic should only be used if configure
didn't find a suitable file locking mechanism or in the event that an
error returned by the locking mechanism indicates something other than
that the file is locked.  If there are no objections, that's how I'll
implement it.
