Sounds similar to what I was thinking about when I proposed this:


Only what I proposed was simpler and non-intrusive, just would require 
setting a LD_PRELOAD as the first line of rc.sysinit.

Benefit of it is somewhat questionable, though, unless you have a big 
system. In reality, zram for swap will give you most of the benefit. The 
big thing is going to be 0-filled pages, and as they are likely to never 
be accessed, they'll get swapped out first, and zram will just throw 
them away.
