NAME

6       ssdd - have a tracer do a bunch of PTRACE_SINGLESTEPs
7

SYNOPSIS

9       ssdd [-f|--forks NUM] [-h|--help] [-i|--iters NUM] [--json FILENAME]
10

DESCRIPTION

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