I noticed this on snap950210, but didn't pay too much attention to it.
Now (snap950322) I decided to enable swap to a file, created /dev/vn0*,
did

	vnconfig -e /dev/vn0b myfile swap

and, surprise surprise, swapinfo says:
		1K blocks	Used
/dev/wd0b	65536		64
/dev/vn0b	1280		64

which is kind of curious, as the machine has 16 MB ram and almost
no activity going on... Swap partition, when in use, are always
reported with at least 64 KB in use.

Is there any explaination ?

	Thanks
	Luigi
