Max filesize for rsync?

Well, I got -further- by changing the fsize= to -1 in
/etc/security/limits on my AIX boxes, 
but rsync ultimately still did not like my 15GB file I wanted to

Had to resort to good ol' plain vanilla ftp.

Please note that, all file size OS limitations aside, rsync has 
suboptimal performance for too big files. When I get around to it I'll

try to create a patch, but in the mean while too big files will have
many non-real hash table collisions, and may become extremely slow.

If you run across this problem, please post on list, as we need someone

to experience this problem in order to try and fix it.
