FYI, I see this also on NetBSD 1.6.2_RC2 i386 :

  PID TT  STAT        TIME COMMAND
    0 ??  DKs      0:-34.36 [swapper]
  257 ??  Ss      -1:-17.23 /usr/libexec/postfix/master
  284 ??  Ss      -2:-6.41 /usr/sbin/cron
  295 ??  Ss      -1:-17.93 fetchmail
  297 E0- S        0:-33.59 postmaster: stats collector process (postgres)

Some days seem to be worse than others. (I can tell by running for
instance "time echo -n" a few times. There are times where this gives
ludicrous results almost every time.)
