Unfortunately returning any real data still loops.
I guess interact is not what I'm looking for, then.

I want a C function (that is a Qt slot which responds
to a signal that the user has hit return in a QLineEdit
widget) to send a string to the Python interpreter
in much the same way as the interactive shell does,
with the interpreter waiting for more input if required.
