I often have simultaneous rsyncs running on a few large but disjoint
trees in the same file system.  rsync's usual mode of operation is
to create a temporary file in the target directory and then rename
it.

Would it make sense to use a global lock only for cross-directory
renames, and not for in-directory renames?
