Its a start, and remember that the counter statement to this is, "_runs_ on
any platform does not require that it _build_ on any platform." The Linux
folk claim to run on the Motorola Coldfire but they don't build there.
What I (and I believe others as well) object to is it not building on a
machine that in its day would support 30 - 40 interactive users and ran the
_original_ VAX BSD.
Also let me caution against too much negativity, performance goals are just
that, a goal that has to be reached. It is like getting the system to
compile without errors. Bloat can be cured by #ifdef :-)

This is fortunately an alternative, a full featured OS with decent
performance. But again, the sky is not falling, it is clearing up. NetBSD
1.5 is a _huge_ advance on the VAX, it runs on lots and lots of systems.
Getting it to run faster is an analysis game with well known rules.
