I don't think what you are seeing is leaks but memory fragmentation.
libc after sarge got really bad with the workload Tor put on its malloc.

Do you want to give the current alpha version a try and let me know if
it helps?  IIRC it reduced memory usage quite some.
My packages are in experimental if you are running sid, or you can use
the backports I put up on mirror.noreply.org as described on
https://wiki.torproject.org/noreply/TheOnionRouter/TorOnDebian
(You want one of the -experimental repositories)
