check_swap quirk on Solaris

[Carroll, Jim P [Contractor]]

On a related note (and possibly of at least as much interest) is the Solaris
notion of 'scan rate', which vmstat reports on.

I've been trying to dig around to see if I can find anything similar on the
Linux side.  I'd think that a quick script plugin which monitors the scan
rate (on Solaris, at any rate) would be desireable.

Any thoughts on what the Linux equivalent could be?
