I have to use pack.threads=1 myself on SMP machines, too.

_SC_AVPHYS_PAGES should probably be accounted for in addition
to _SC_NPROCESSORS_CONF when calculating the default pack.threads value.
Calculating good defaults is hard, though...

I've also been meaning to try the newer tombstone-free khashl
to replace khash in our tree for memory savings:

Perhaps you (or someone else) can take the lead, there.
