Answer 1

If your method "processDoc" doesn't change any other data (just looks for some data and return it and don't change variables or properties of parent class) you may use Py_BEGIN_ALLOW_THREADS and Py_END_ALLOW_THREADS macroses ( see here for details ) in it. So the document will be processed in thread which will not lock the interpreter and UI will be updated.
