Or I could run with overcommit turned off, but we like overcommit because
things like vaccuum appear to allocate maint_work_mem when they start, so
if that is set at say 100 Mb it will allocate 100 Mb even to vacuum a 2
page table. Overcommit lets this sort of thing get by without createing
a need for even more swap.
