I'm with you up to here.

The way we handle different runners/os can be categorized as "tested in 
gate", "unsupported" (should work, possibly some hacks needed), and 
"hostile". At present, both nose and py2.6 I would say are in the 
unsupported category. The title of this message and the content up to 
here says we are moving nose to the hostile category. With only 2 months 
to feature freeze I see no justification in moving py2.6 to the hostile 
category. I don't see what new testing features scheduled for the next 
two months will be enabled by saying that tempest cannot and will not 
run on 2.6. It has been agreed I think by all projects that py2.6 will 
be dropped in J. It is OK that py2.6 will require some hacks to work and 
if in the next few months it needs a few more then that is ok. If I am 
missing another connection between the py2.6 and nose issues, please 
explain.
