By chance, I'm reading _Sunburst_ and on P.96 they mention Joy taking
a class taught by Dave Patterson.  Is this the same class?

That's one of the funniest things about Unix-like things over the years....
duplication of effort. How often has the same system-call or editor or
window manager been re-written. Too bad we can't retain all these

I noticed that Peer-to-Peer press is printing all (6?) of Jolitz's books
of commentary on BSD kernel code.

I had looked a little through Lion's commentary.... anybody know the origin
of the name of the function "estabur()"?  And one more.....
the origin of the name "channel", as in wchan?
