This is just to report that this issue is resolved (for me). Tres
Seaver kindly provided a patch for HTTPRequest.py that makes the
environ dictionary immutable (appended below for those in a similar
position). This may have adverse consequences for applications that
rely on existing behaviour and Tres has recommended that it would be
better to harden the User Folder code. In our case we might also be
able to encrypt the remote Username. Once again, thanks to Tres and
other list members, who are a wonderful resource.
Completely immutable environ is not a good choice from WSGI
point-of-view. environ can be useful for middleware information-passing.
