And it's important to note that the destructor doesn't get called
*immediately* that happens; rather, the destructor will be called *some
time after* the last reference to the object is gone.
In short: you can't force Python to invoke the destructor at any
particular time, and hence your code shouldn't assume that it will
happen at any particular time.
