I believe the issue has to do with the OS X application firewall and not
sandboxing, as vanilla Python on OS X is not sandboxed. See:
As described there, codesigned applications are automatically authorized
to accept inbound connections; that's the workaround proposed in the
apple.stackexchange cite. But arbitrarily signing development binaries
after every compile is probably not a good idea. Another option is to
configure the firewall but that probably only can be made to work with a
framework build of Python which launches Python within an app bundle.
In any case, please open an issue on the bug tracker so we can follow up
