Dangerous Bug

Being a ridiculous geek, even being in Japan doesn't stop me from reading, for instance, the release notes to the latest Python 2.4 beta. Here was one of the bug fixes:

Bug #1055820 Cyclic garbage collection was not protecting against that calling a live weakref to a piece of cyclic trash could resurrect an insane mutation of the trash if any Python code ran during gc.

If you see anyone in lab spurting blood from his severed neck, chances are he was gored by an insane mutant resurrected from the dead. Glad they fixed that one.
