Antoine Pitrou <pitrou at free.fr> added the comment:
The following works (2.6 and trunk):
import ctypes, thread
ctypes.pythonapi.PyThreadState_SetAsyncExc(
ctypes.c_long(thread.get_ident()),
ctypes.py_object(ZeroDivisionError))
for i in range(1000): pass
The thing to remember is that PyThreadState_SetAsyncExc() is
asynchronous and doesn't guarantee that the exception will be raised
timely (that's why I added a small busy loop above).
