Id want it global. Otherwise Id subclass IO::Handle and instantiate that class instead; that works just as well and wont conflict with anything else.

How does overriding DESTROY break thread safety?

Makeshifts last the longest.

    If you attempted to limit the effect of the change to that one function (and those it calls) using local *IO::Handle::DESTROY = sub { ... };, your code wouldn't be thread-safe.
