stupid optimization hack

Stupid  optimization  hacks: Instead of keeping the limit in a register, keep
limit - 512 in a register.  Now, when ever you are going to do a check to see
if  there  is  enough  space,  if  you want 512 bytes or less, just check the
frontier against the limit - 512.  This might  cause  you  to  GC  512  bytes
early, but who cares.  A stupid hack, but perhaps worth while.
