    More useful script output.
    
    Overall performance numbers are still bad.  Presumably having a single
    global PKCS #11 lock does not help here.  Need a bitstream with more
    ModExp and ECDSA cores before this will matter much, but will likely
    need to figure out some way to do per-session locking instead of
    global for operations we want to run in parallel.  At which point
    we'll be on the road to deadlock hell, so will need some care.
