I have done 700k and 800k files transfers (including hardlinks), but 
indeed it could take a while to compute the transferlist. Newer rsync 
versions bring down the amount of memory needed drastically. That is one 
of the reasons I offer a recent rsync in RPMforge. There is almost never a 
good reason to use a dated rsync.
