There isn't threading any there to rip out, except for the one hack to avoid
stalls on DNS lookups.  Different part of the code.

There was code for signaled asynchronous packet I/O.  Hal thinks it
was a hack to get around not being able to get real arrival timestamps
from the packet layer. He's probably right.

I took it out because the NTF build had an assumption built in that
that it didn't work on basically any modern Unix - I doubt it had even
been compiled in a decade.
