That's kind of already possible, but it's currently only build-time
configurable. (Look for MINHINCR and MAXHINCR.) I think there's no good
reason for that, since it's rarely accessed. (It's currently expressed
as a multiple of the minimum heap block size. That would need to be
fixed.) If someone wants to submit a patch ...
