Looking at the log from sage-2017-03-10_21:25:42-rados-wip-mgr-commands---basic-smithi/902188...
Seems like this is happening on the second call to PyModules::init (the daemon went inactive then active again, which it's allowed to do).
I think there's just no call to PyModules::shutdown anywhere, which would have been calling Py_Finalize and making the second call to Py_Initialize safe
