I don't think it's a good idea to have stock circle use such systems to
reduce memory usage.
This should be a patch or snippet...which it is--and should remain so. I
think what stock Circle should include are faster, better, speedier
things--not memory-conserving things...of course, in this case you can have
the best of both worlds...
I'll submit some code/more specific ideas when all this schoolwork is done.
