[issue1805] sysctl needed for taking swap statistics

[Matthew Dillon]

:Hi! Thanks for your quick answer.
:
:The new sysctl will be useful, but i'll need to retrieve individual swap device
:stats too. Are you (or anybody else) going to create this one?
:
:In that case, can we leave this issue open until it's created?
:
:Regards.

    Hmm.  We don't record individual stats at the moment, which is why
    the libkvm code has to scan the blist (which is slow) to figure
    it out.  It would be fairly easy to add tracking for each device,
    I'll see if I can work something up quickly.
