horrific performance with trivial operations such as portsnap fetch update

[Dennis Clarke]

This seems terribly wrong :

eris#
eris# /usr/bin/time -p /usr/sbin/portsnap fetch update

Not sure where the problem is however this is a very new install :

eris# pkg query %t\ %n\ %v\ %o | sort -r

However I am running with kern.smp.disable=1 but that can not account
  for this sort of a performance penalty.
