Tuning kern.maxswzone is minor compared to hangs in "kmem a" state

So next time this happens, run "procstat -kka" - this will dump out
the processes and a basic function call trace for each of them.

I'll see if there's a way to teach procstat to output line numbers if
the kernel debug image is available, but generally that's enough to
then pass to kgdb to figure out the line number.
