[Python-3000] sys.exc_info()

Hello again,

Yes it's a possible implementation. At the expense of a performance hit for
operations which currently use tstate->exc_* (sys.exc_info() itself, bare
"raise"...).

Right now I have a patch using my original implementation proposal. I'll post it
soon.

regards

Antoine.
