Robert Collins 6bc2c1e7eb Issue #17911: traceback module overhaul
Provide a way to seed the linecache for a PEP-302 module without actually

Provide a new object API for traceback, including the ability to not lookup
lines at all until the traceback is actually rendered, without any trace of the
original objects being kept alive.
