[erlang-questions] Difference of gigs between beam.smp memory and erlang:memory(total)

[ori brost]

I've been doing a simple experiment in which I attempt to connect
about 500000 websocket clients to RJ's websocket patched mochiweb
fork. I've noticed that there is a difference of several gigabytes
between memory consumed (I'm talking about working set here, not
virtual) by beam.smp and the value returned from erlang:memory(total).
Could this be related to the problem in
