The change you're talking about does most likely not fit into a bugfix
release, given how much code in the snapshot has changed related to
file and pipe access.

You observed this behaviour, you're the guy who can help.  Using gcc and
cvs you should be able to find out which change after the 2007-08-13
snapshot slowed rsync down again.  If you found the change, I'll look
into it.  Promised.
