Swapping? On a recent version of Solaris?

Presumably paging would hurt as much. But I can't think of anything in
recent versions of Solaris that would make it less prone to swap than
other versions.

Well, I was using an unusual definition of "recent". I was thinking
"2.5.1 and later", where actual swapping is very unusual. So I'm not
sure what read/write activity would be done on the flash drive (aside
from a system image upon a crash).
