Yeah, that's a different thing. I said it stands Stackless so far,
but you cannot expect any IDE to get debugging right if it
doesn't know about tasklet switching.

You seem to be quite new to Python, btw.

Be just careful with print. PythonWin uses the Scintilla control,
which is not reentrant. Printing that much as you did is anyway
no good in PythonWin, it seems to freeze because it has todo so
many screen updates and appends to the display control.
Try short programs with not so much output which terminate,
and don't rely on the debugger. Breakpoints will not work
if the stack is not as expected.
As said, it normally doesn't crash with Stackless, but don't
expect that the IDE helps you very much.
