  running gc on cadr4, it actually wins fairly well! however,
it can be made to drop dead (mostly by hacking with multiple
processes with the mouse).  Some of these drop deads appeared 
semi reproducable.  P-N-STRING was pretty well garbaged.
the gc-pointer for the initial 300000 size region was 300000
and for the other region 0, so maybe the scavenger had just
completed scavaging that region and got out of phase and
garbaged it instead.  Was not able to get any real evidence
tho.
