have a tracer do a bunch of PTRACE_SINGLESTEPs


ssdd <options>


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.


-f,  --forks
number of tracer/tracee pairs to fork off. Default is 10.
-i,  --iters

number of PTRACE_SINGLESTEP iterations to do before declaring success, for each tracer/ tracee pair set up. Default is 10,000.

-h,  --help
