There are no known issues, except maybe PyQT.

Recompile Stackless with STACKLESS_OFF defined.  If it is easier, you
can edit Stackless/stackless.h and change:




Then it should compile to normal Python 2.7, and you can see if System
imports then.  If it does not import, then this is a general
non-Stackless related problem.  If it does import, then I guess we
have a problem.

Alternately, if you don't want to use the preprocessor define, you can
just get the source for Python 2.7, compile it, take the python binary
and replace the Stackless python binary with it.  Then see if System
imports.  Same difference.
