Eddie Hebert 1ddfadf5b4 Recycles the portfolio container to be passed to handle_data.
The creation of a new portfolio ndict on each call of handle_data
was creating a very high performance overhead.

Instead, we use the same the portfolio object for each event,
and replace the values contained within.
