.SH NAME
ssdd \- have a tracer do a bunch of PTRACE_SINGLESTEPs
.SH SYNOPSIS
.B ssdd
.RI "[nforks] [niters]"
.SH DESCRIPTION
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.
.SH OPTIONS
.B nforks
number of tracer/tracee pairs to fork off.
Default is 10.
.br
.TP
.B niters
number of PTRACE_SINGLESTEP iterations to
do before declaring success, for each tracer/
tracee pair set up. Default is 10,000.
