Regardless, all your suggested changes still improve the capability of
rsync to run simultaneously on the same tree, so it sounds good. My
one niggle is that always keeping the token in the temporary filename
without any special-case truncation would allow users to have stronger
guarantees about excluding these files.

How about rsync trims just the original filename portion, and if it
reaches zero characters and even '.XXXXXX.rsynctmp' doesn't fit, error
out. If we want to keep going, rsync could try fewer X's down to zero
and eventually try the 9 char '.rsynctmp' filename.

(Well, one problem with the above is the exclude pattern would have to
be .*rsynctmp, so you could give up at the 11 char '.A.rsynctmp'
instead.)
