FWIW, I got the impression at the time (but I don't remember why; I
think I was half-guessing based on assumptions about what it does and
several iterations through the documentation) that it was
fundamentally only *able* to do compaction during the stop-the-world
pause after a concurrent mark phase. I.e., I don't think you can make
it spread the work out (but I can most definitely be wrong).
