A separate GIL for each one? No; numerous read-only and immutable objects (e.g. the small integers, 1-character strings, the empty tuple; and all built-in type objects) are shared between all interpreters. Also, extensions can easily share state between interpreters I believe.
All extensions share their state between interpreters. The import machinery literally caches the module dict for an extension and uses that to reinitialize any new instances. But Martin's PEP on module init helps to deal with this issue. -Brett
