It depends on what version of rsync you're using.  Older versions would
allocate an additional file list for --delete, and another for -H, so
memory use is much more efficient in a modern version.  Also, if your OS
doesn't use copy-on-write memory when the receiver forks the generator,
you'll see a doubling of the memory requirements on the receiving side.
