This must be addressed one way or the other. Otherwise you will break
isolation of sub interpreters. Builtin objects, types and methods *must*
be immutable because they are shared across subinterpreters. This topic
has been addressed by the PEP.

Proposal:
You could store the signature objects for builtin methods in a dict in
each PyInterpreterState and use the qualname to reference the signature
object. This ensures full isolation.
