+This valid code doesn't work at all. The mainthread object in MTinterface
+is not properly initialized, the cancel_event is NULL and the win32_obj_id
+is NULL because myself->hProcess is NULL when MTinterface is initialized
+(and i don't think that a process handle can be used as thread handle).
+Even if the handles would be valid the pthread_join call would try to
+delete a thread object that is created static which would result in a
+corrupted heap.
