too_many_results error

Hi Eric,

This is a failsafe that is applied prior to the 'rows' parameter.

It is applied separately to provide a hard system limit, intended to allow
the cluster administrator to guard against a malicious user, a client
application that accidentally requests too much data, etc.

Best,
Rusty
