I don't know the internals of how svn does its binary diffing... But from my
past experences with other binary diff tools, it is VERY memory intensive...

I have worked with bsdiff, which takes around 17 times the size of the file to
do its diffs... http://www.daemonology.net/bsdiff/

Granted this is a little extreme, but in general, unless you really are making
small changes to binary files, as opposed to not outright changing them
dramatically, this may not be the best tool for the job...
