[Stackless] Still getting crashes with PySide

I have to admit that I didn't build Stackless on Windows for a long time.
But Visual Studio 2008 works definately.
There is also a pip version in the works, stackless as a pseudo-plugin...
Well, to build it if you have Visual Studio, take the whole project download
hg update v2.7.2-slp
Then open the project with Visual Studio in pcbuild, select the
right version for building (32bit, since PySide is 32bit)
and compile it.
The notes on cpython are applicable as well:
and the express version of VStudio 2008 should work (but I never used it)
