Not sure this is a memory leak, but i have my doubts that this is an intentional feature.

All the observations that follow refer to code freshly pulled from the trunk.

When running the simulation (without any digitization), the json output file gets a new line for each spill we run. The number of hits in the "mc" branch of each new line grows with each new spill. Shouldn't there be a reset? If we try to run a large number of events, the memory consumption becomes unbearable at some point. (Had to restart my laptop when trying to run 1000 spills).
