That's interesting, but not really appropriate to my situation - bzip2 and
LZMA are hundreds of times too slow to be used for local revlog storage.
Even bzip2 or LZMA in the wire protocol makes a poor fit for fast WANs, as
they reduce bandwidth (abundant) at the cost of increased CPU (scarce on
the server).
