For what its worth, rather than just saying which one is "better" and
forcing that option on users, I would like to see both (and more
options) implemented and have a way to select between them at compile
time or wherever is convienent.

Is there a way to measure the space usage difference?  We have hard
jemalloc numbers that show a benefit, and I'd like to quantify any
counter-arguments.
