Yes and no. As I indicated in my prior reply at
in your specific case the qrunners don't have permission to write the
.pyc so it can't be updated. This is not a problem in that Python will
always use the more recent .py, but there is innefficiency in that
since the .pyc can't be written, the .py will have to be compiled each
time it is imported.
