I was working with the freshly reinstalled 3.2 which is not the same as a pristine 3.2 install because it still had the problem that 3.2.1 has and the 3.2.1 sys.version. 3.2.1 uninstall in not complete (a different issue). So I should reinstall 3.2.1 again and try again.

I agree about fully switching t. subprocess. If self.rpcpid is not used anywhere other than unix_terminate (which I think should be renamed)), then self.subproc could replace self.rpcpid.
