Can I suggest that a quick test could help determine that if you have 
some free IO?  Perhaps create a small script to "touch" files with 
random names in the style /a/b/c (to avoid overloading directory indexes 
on certain file systems).  Perhaps plot a simple chart of space required 
versus number of files (each 0 bytes in this scenario)

I suspect you will find you are right... One of the major optimisations 
of the new rsync is in decreasing memory required per file tracked.  
Seems like a fairly thing to estimate anyway

Good luck!
