Don't leak a 16k allocation if PyArg_ParseTupleAndKeywords() or the first xc_readconsolering() fail. It is trivial to run throught the processes memory by repeatedly passing junk parameters to this function. In the case that the call to xc_readconsolering() in the while loop fails, reinstate str before breaking out, and passing a spurious pointer to free().
