For the disk to be hit during compiles? Yes. I don't know about having
that little memory left... Or the vmstat statistics. It's possible
that there is a bug. I'll look into it. The 1.8M is what's left after
the kernel has allocated all its data buffers. If I'm not mistaken, it
can grow beyond that...

Yes. Just once. When I had compiled NFS stuff into my kernel. Does
it happen if you don't config in netstart? Which kernel are you running?

Yes. You need to reconfigure the kernel and recompile. I haven't tried
two slip interfaces before ;-)

oops. That's been added to the to-do.

Constantly fast--as in it's still off by the same amount an hour later?
I have a problem with my SE/30 in that the clock is almost never read
correctly... I get dates that range across a century.
