I'm running a custom XENU kernel with COMPAT_BSDPTY and the pty
pseudo-device built from netbsd-3 sources dated 20060416.

When I run the python-2.4.3 regression tests, I consistently panic
the kernel with the attached result.  This happens during the "openpty"
test.  You can run the python regression tests without installing the
python package by doing:

	cd pkgsrc/lang/python24 && make test

(this package should have no dependencies on a normal NetBSD system).

	Cheers,
