Does freebsd's implementation of ptrace support a
child ptracing it's parent (non-child ptracing)?

I'm told it does, if so, could anyone give me a small
example, or give me a clue why waitpid is giving me
this error after i attach:
waitpid: No child processes
Of course there are no child processes, but you have
to do a wait after you attach right?
