[LLVMdev] [RFC] Requiring python 2.6

[Rafael Espíndola]

Currently lit on windows will not work with python 3 because the
internal shell has code like

 except OSError, e:

and in python 3 one has to use

 except OSError as e:

But that only works on python 2.6 and newer.

So the question is: any objections to dropping support for python 2.5?
Python 2.6 was released 01-Oct-2008, so it should be available
everywhere.

Cheers,
Rafael
