You're getting out of python-dev territory now - I'm happy to help with some tips on interpreter internals, but I'm not going to attempt to debug-from-afar a modified version of the interpreter (particularly when the problem relates to file permission issues which are highly OS and file system dependent). That said, the usual debugging tactic of divide and conquer (e.g. adding trace calls to figure out exactly which step is failing, or just calculating the hash without attempting to write it to disk) will probably be your friend. Failing that, you might want to try asking for further assistance on comp.lang.python (aka python-list at python.org).
