Hi William,
I don't know precisely but in case it can help I would raise that the main
difference between step() and run() is Py_BEGIN_ALLOW_THREADS, at least if
O.run(...,wait=True).
Do you have the same problem with and without "wait"?

Simply passing to c++ a python expression (just a string with python
commands) or a python function returning a value - instead of a derived
class object - could be a simple workaround maybe.
