Note that a number of the changes listed below were not applicable to the Py3k branch, and hence the corresponding files are unchanged in this checkin. This checkin is also the first time the environment checking in regrtest has been forward ported to the Py3k branch. This checkin causes test_xmlrpc to fail - see issue 7165 (it's a bug in the 3.x version of xmlrpc.server) I am also getting a failure in test_telnetlib, but it isn't clear yet if that is due to these changes.

Note that a number of the changes listed below were not applicable to the Py3k branch, and hence the corresponding files are unchanged in this checkin. This checkin is also the first time the environment checking in regrtest has been forward ported to the Py3k branch. This checkin causes test_xmlrpc to fail - see issue 7165 (it's a bug in the 3.x version of xmlrpc.server) I am also getting a failure in test_telnetlib, but it isn't clear yet if that is due to these changes.
