My proposal is to implement pointer sampling in the GC (using

able to specify how much % we'd like the GC to swipe on average
at every cycle, so that these cycles run less frequently.
Now I understand what you mean.
I think this is an interesting idea. I've used the idea of
reducing collection frequency to trade off running time for peak
memory usage before.
I would be interesting to have these "knobs" available to turn to
tune application performance.
I think we should do something similar to CDGC for this: use
environment variables to set the settings at initialization time.
