sears dad55b564c Misc statistics cleanup; improved merge cost estimations during backpressure. 
Misc statistics cleanups include:
 - fixes for corner case where c0 is empty, and it would divide by zero
 - always compute number of tuples (in / out, but not base)
 - rework amount of memory allocated when --test and --newserver are passed in.
