This Python "feature" has been here for so long, I assumed it was supposed to work this way... Problem is when a control-c is typed, it does a CORE DUMP! OpenBSD 3.2, 3.1, 3.0, 2.9, and beyond. i386 build. Standard PC. Python 2.2.2, 2.2.1, 2.1, and beyond. Standard build.

You can report it, but not here. Please use sf.net/projects/python to report bugs.

>>> pid 1234: Fatal error 'pqinserttail: Already in priority queue' at line 196 in file /usr/src/lib/libcr/uthread/uthreadpriorityqueue.c (errno = 4) Abort (core dumped)

Notice that this is a failed assertion in the C library of your operating system. It should not be possible for applications (Python or other) to trigger assertions in the C library, so when this happens, it indicates a bug in the system.

Python might be using the C library incorrectly, though; please add -D_THREADSAFE to your Python compilation and see whether this changes anything.

If this really is a bug in the system, you should configure Python with --disable-threads.
