Count me as "not surprised". Unloading modules before exit is all very
well, but hanging if they won't unload is just asking for trouble.

No, it's simpler than that. Just ignore errors; *attempt* to unload
each module, but leave it if it doesn't unload.
Forcing an unload when the module's code may be on the call stack seems
dangerous, and will at least be confusing to those using debuggers.

Yes. That patch isn't necessary if you just ignore errors.
