Subject: /dev/swap acting weird?

When my Magnum cpuserver boots, I don't have any swap configured.
At that time, here's what /dev/swap reports (I'm bootes on the console):

plan9% cat /dev/swap
304/4300 memory 0/19200 swap

I have 2 identical disks on this system, and I used disk/prep to create
a different sized swap partition on each one. However, when I use
the swap command to enable swapping to these devices, the 'total available'
field doesn't change at all:

plan9% ls -l /dev/sd*swap
--rw-rw-rw- w 0 bootes bootes 35225600 Sep 27 09:59 /dev/sd0swap
--rw-rw-rw- w 8 bootes bootes 67108864 Sep 27 09:59 /dev/sd1swap
plan9% swap /dev/sd0swap
swap: /dev/sd0swap
plan9%
plan9% cat /dev/swap
305/4300 memory 0/19200 swap
plan9%
plan9% swap /dev/sd1swap
swap: /dev/sd1swap
plan9% cat /dev/swap
305/4300 memory 0/19200 swap

I was expecting it to track the size of the swap partition in use.
Am I missing something?
