:...also vmstat seems to exist in a few other OSes (linux e.g). maybe they've
:fixed it already (or the netbsd/openbsd/dragonflybsd folks or apple?).

:cheers.

No, we haven't. I think it is meaningless too, and I can't imagine
any script that would try to snarf that line.
Another problem is that vmstat output in general is blowing out its
column formatting.
We have made some changes in DFly... sub-second intervals can be
specified, and I think we enforce at least one space between fields
so the output doesn't become totally unreadable. But the blowouts
still remain.
