add sleep, allow errno '3' (ESRCH) on the open of /proc/pid/cmdline

The sleep is added here simply to not completely spin cpu on waiting
for the parent pid to die.

the allowing of errno 3 is because I was getting this.  I dont have
a perfect explanation, but I suspect that the 'open' was actually
getting this back from the /proc filesystem after the pid had died.
Possibly in the window between when the 'open' was done and the 'read()'
was done.
