If we are going to do something like that we should probably just go by
block size to decide if we should do the compression and do the thing
with keeping the most recently used LZO block (or perhaps a few)
uncompressed in RAM for speed.  Probably also look at the compression we
get when we decide to compress and not bother doing the compression if
it's a small saving, though we will have burned CPU.
