UNIX version 2*pi

One of my predecessors at JHU decided 6.06 was a nice symmetrical number and
stuck the version there through many kernel changes.   When he left, our
release numbers started forward again.

The BRL/JHU kernel was based on V6.    It had a kludge to allow more that
256 users but eventually, we widened the UID/GID to 16 bits each.   We then
added a the ability to mount either V6 or V7 file systems (we had a lot of
removable V6 FS media).

Sounds like the one I was maintaining at UNSW: Edition 6, with the bits of
Edition 7 that would fit on an 11/40 and 11/60, plus local AUSAM stuff.
