pyvm -- faster python

Hi.

pyvm is a program which can run python 2.4 bytecode (the .pyc files).
A demo pre-release is available at:
	http://students.ceid.upatras.gr/~sxanth/pyvm/


Facts about pyvm:
- It's FAST. According to the "cooked-bench" benchmark suite it finishes
   in 55% of the time python takes;)
- It's SMALL. Currently the source code is under 15k lines with the
   builtin modules.
- It's new. Uses no code from CPython.
- It's incomplete. Not even near the stability and quality of python.
   It needs A LOT of work before it can be compared to CPython.
   Moreover, at the time it lacks many things like closures, long numbers
   new style classes, etc.
- It's incompatible with CPython. Not all programs run.
- The C API is incompatible. You can't run C modules (a thin wrapper to
   make pyvm appear as libpython *could* be possible but not a goal
   AFAIC)
- The demo is an x86/linux binary only. You shouldn't trust binaries,
   run it in a chrooted environment not as root!

Hope it works!

Cheers,

Stelios
