Summary: update to PEP 344 - exception attributes

Initial Comment:
PEP 344 proposes adding __traceback__, __context__, and __cause__ attributes to Exception.

The primary objection has been that the __traceback__ exception would cause a cycle, which would delay resource release.

This objection is now added to the PEP, along with some details about why it is a problem, and why weakrefs aren't a straightforward solution.

Guido said he could check it in if Ping agrees, so I'm assigning the patch
to ping (who I *hope* is Ka-Ping Yee)
