My concern over the PMMU potential argument goes like this:  MCL is in the
foreground.  It's memory is fully "real", and the PMMU reflects that.  Now
MCL goes into the background and later RAM Doubler decides that MCL is
"inactive".  Now RAM Doubler goes in, moves MCL's memory around, steals the
unused parts of the heap, etc, adjusting the PMMU to reflect what it has
done.  Now the ephemeral garbage collector decides to run.

It's not immediately clear that all is well.  It's also not at all clear
that there's any problem.

It does need to be looked at in a non-mission-critical environment first, I
would think.
