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
  It looks like the extra spage usage was fixed by Jason Evans around
March. The Google link provided by Freddie Cash pretty much covers
every info you needed. I can perform further benchmarks if needed. But
I think I'll not do it, given the reluctance on the list. I'm
certainly not the best judge for this level of technical detail.
If it's there, and you can see it, it's real.
If it's not there, and you can see it, it's virtual.
If it's there, and you can't see it, it's transparent.
If it's not there, and you can't see it, you erased it.
