New description:
In the file `sage/tests/interrupt.pyx` there is a test for a segmentation
fault by explicitly dereferencing a NULL pointer. However, on some
systems (Mac OS X 10.4 PPC, Mac OS X 10.4 Intel, and Mac OS X 10.5.8
Intel) this generates a SIGBUS instead of a SIGSEGV.

Comment(by GeorgSWeber):
I see this on MacIntel OS X 10.4.11, too, so I updated the description.
The patch looks superb (although I didn't apply and test it myself);
hopefully it gets into the next alpha/rc release.
