[Stackless] python 2.8 slp (Re: Fwd: [Stackless-checkins] stackless (2.7-slp): add a filter function to zipfile.PyZipFile.)

now I have a good reason for 2.8. I would like to:

- switch compilers on windows to VS2010

- only add features if they are in Python3 as well

- maybe remove bsddb (because 3.x tossed it)

I am working right now with a windows 2.7 version that I modified for 
but life would be much easier if we decide to make the compiler transition.
Because no official 2.8 will exist, this is a fine move.

Also I struggled quite a lot buildin pywin32 for it. With 2.8, this will 
no new special version, but the transition can be very easily done. 
pywin32 decides by

         # vs2008 or vs2010
         if sys.hexversion < 0x3030000:

which could become

         # vs2008 or vs2010
         if sys.hexversion < 0x2080000 or sys.hexversion in 
xrange(0x3000000, 0x3030000):

And python 2.8 without stackless is implicitly possible by defining 

Any objections?

all the best - Chris
