[issue30744] Local variable assignment is broken when combined with threads + tracing + closures

[Nathaniel Smith]

Nathaniel Smith <njs at pobox.com> added the comment:

@arigo: But CPython is already committed to supporting writes to locals() at any moment, because at any moment you can set a trace function and in every proposal trace functions can reliably write to locals. So I don't think this is a serious obstacle for addng a JIT to CPython -- or at least, it doesn't add any new obstacles.
