UNIX continues!

>From what I remember reading (QUITE a while back), HALTing the CPU isn't
a really great idea.

On the pdp11's, the UNIBUS behaves differently when the CPU is halted. More
specifically, NPR requests fail, and so (older) disks can do unpredictable
things if a transfer is occurring when the CPU is halted. (Really, decvax!aps
is one of the people who come to mind on this. Armando?)

As I said, it's been a while since I've looked at the material on this, but
you are VERY, VERY wrong in the statement that "a partial sync() is better
than no sync() at all."
