This does make me wonder... while the example I am going to use is somewhat
obsolete, it's an extreme example of something that can still happen.

Somewhat infamously, if you do not use a no-rewind device, close() blocks
unkillably in the kernel until the tape is rewound. What happens if this
occurs during finalization in the garbage collector?
