    subprocess: always pump default main context in main thread
    
    If we are in the main thread (ie: the gtk thread), we want to pump the
    real main loop rather than our own main context. This keeps gtk responsive
    should it be necessary as well as ensures that we will get our dispatch
    called (which could end up having landed on the primary main context).
