Unfortunately, the current implementation is processor-dependent; it
supports x86, SPARC, and PPC only (not really sure about PPC). It also
limits extensions: if they call back to Python, they must not keep
"global" variables on the stack (global in the sense that their
address is known outside their function).

These limitations require Stackless users to be more aware of the
inner workings of Python, or they risk crashes - something that would
be considered a bug in standard Python.
