Hello Squeakers,

I'm pleased to announce that I'm finally finished with the latest
version of VI4.  You can get it from its usual place at
http://minnow.cc.gatech.edu/squeak/VI4.  It has been rewritten and
cleaned up and should be very stable.  Once other image format changes
are incorporated (if any) and once it is approved for a future Jitter,
it should be ready for prime time.

The Interpreter still operates directly on the process stack object, but
hooks have been provided so the process stack can be internalized by the
VM if desired.  See the aboutVI4 method comment for more details.

0 tinyBenchmarks reports a 30% increase in bytecode speed and a 75%
increase in send speed.

Enjoy!
Anthony
