Patch by Jonathan Wight (slightly reformatted) to forestall loading the same module twice, which apparently crashes Python. I could not test the error condition, but in normal life it seems to have no adverse effects. Also removed an unsued variable, and corrected 2 glaring errors (missing 'case' in front of a label).
