Notice that at least the following objects are shared between interpreters, as they are singletons: - None, True, False, (), "", u"" - strings of length 1, Unicode strings of length 1 with ord < 256 - integers between -5 and 256 How do you deal with the reference counters of these objects?
Also, type objects (in particular exception types) are shared between interpreters. These are mutable objects, so you have actually dictionaries shared between interpreters. How would you deal with these?
All these should be dealt with by making them per-interpreter singletons, not per address space. That should be simple enough, unfortunately the margins of this email are too small to describe how. ;) Also it'd be backwards incompatible with current extension modules. James
