At least two. The 0 above was so shocking so I ran that test five times,
I think. :)

Me too. I tested this for a completely different reason: without PAE, my
Tails VM (VirtualBox) often freezes when I run many fillram in parallel
during a wipemem test. I wanted to check if similar freezes happened
when many sdmem are run in parallel. It never froze, but instead I found
this discrepancy. Lucky catch.
Cheers!
