That's not unique to Managed C++. Controlled objects in Ada
can have their destructors called multiple times as well. If
it matters, you must keep a flag or other indicator (such as
nulling a pointer) to see whether you have been destructed.
And Ada doesn't even have (i.e., require) garbage collection.

This fits in with the UNIX philosophy of solving 90%
of the problems and ignoring the final hard 10%. That
way most people get the benefit of a simple system,
and the people who create complexity get what they
deserve by having to deal with it themselves.
