I'm very happy to tune the heuristic further.  It can be wrong in both directions.  ORWT didn't have this problem because it only ran one copy of DRT.  NRWT can run as many as we'd like it to (you can manually control it with --child-processes=N as you like).  Right now it tries to run one-per-core if we have the ram to support them.  The RAM requirement was added because we were breaking the Mac builders which only had 3GB of RAM :) (Which was about all you needed back in the day to link webkit and run one DRT at a time.)
