Note that even leaving out the garbage collector, the cPython VM
incrementing/decrementing the refcount of objects will force the copy.
The python multiprocessing module has some classes which allow
explicitly sharing memory. Certainly for various caches e.g. if
they're just read-only after a certain point it might make sense
to wrap them in e.g. a multiprocessing.Value.
