Apropos of nothing, but...

are not necessarily _in_creases, and may well be mostly _de_creases.
e.g., on a RELENG_9 box with 8 gig of physical RAM:
% sysctl kern.{max{d,s},dfld}siz
kern.maxdsiz: 34359738368
kern.maxssiz: 536870912
kern.dfldsiz: 134217728
while a -CURRENT box with 16 has dfldsiz blown all the way up too. I
don't recall doing anything to change them at all recently, and a
glance over loader.conf, sysctl.conf, rc.local, and the kernel configs
doesn't turn up anything.
