Summary: UUID bugs: last_clock

Initial Comment:
I'm looking at your UUID class http://trac.labnotes.org/cgi-bin/trac.cgi/browser/uuid/lib/uuid.rb and am puzzled by two things:

* line 202 you have "elsif clock = @@last_clock", that's an assignment that will always evaluate to true as far as I can tell

* if you change 202 to ==, then the combination of 205 incrementing @@last_clock by 1 and the masking of the lower-order bits of the time in  line 198 will make it that the next time you generate a UUID withing the same clock tick the clock is less than @@last_clock, which is not what you intend.

I'll see how I can fix this on my end. Thanks for making your class available!
