It does sound like a problems somewhere in the garbage collector.  It seems like the garbage collector is trying to keep the reference that rightfully belongs to you.

Have you tried taking out your calls to CFRelease and forcing the garbage collector to run every iteration through the loop as a test (say by calling GC.garbage_collect). Seems a bit extreme, but it would let you know if the ruby proxy wants to "own" your CG objects for you.
