       Have  a  tracer  do a bunch of PTRACE_SINGLESTEPs against a tracee as fast as possible. Create several of
       these tracer/tracee pairs and see if they can be made to interfere with each other. The tracer  waits  on
       each PTRACE_SINGLESTEP with a waitpid(2) and checks that waitpid's return values for correctness.

              Display usage

       -i,--iters=NUM
              number of PTRACE_SINGLESTEP iterations to do before declaring success, for each tracer tracee pair
              set up.
              Default is 10,000.

       --json=FILENAME
