Re: 3x faster python reader

This sounds awesome!  Is the API compatible with the existing API?  If
it's incompatible and cannot easily be made compatible then perhaps we
can add it as the 'new' API and deprecate the old one.  Regardless,
please file an issue in Jira (issues.apache.org/jira/browse/AVRO) and
attach your patch there.
