I have always rejected overcomplicating rsync with cache control code (the
complexity of a --drop-cache patch I saw was quite horrifying).  In the
past I pointed people towards https://github.com/Feh/nocache as one way to
get posix_fadvise used by an rsync copy.  That project now apparently
suggests creating a memory-bounded cgroup, which sounds interesting.
