Ok. Thanks for the clarification.

Many thanks! 

But one other thing regarding call_pydb(). And I'm not really sure how
to fix. So if anyone has suggestions...

pydb.runv() should be using the ipython Pdb class which has pdef, pdoc
commands added and not the pydb one.

Well, in the os module there is: 
  execl(	    path, arg0, arg1, ...)
  execle(	    path, arg0, arg1, ..., env)
  execlp(	    file, arg0, arg1, ...)
  execlpe(    file, arg0, arg1, ..., env)
  execv(	    path, args)
  execve(	    path, args, env)
  execvp(	    file, args)
  execvpe(    file, args, env)

  spawnl(	      mode, path, ...)
  spawnle(      mode, path, ..., env)
  spawnlp(      mode, file, ...)
  spawnlpe(     mode, file, ..., env)
  spawnv(	      mode, path, args)
  spawnve(      mode, path, args, env)
  spawnvp(      mode, file, args)
  spawnvpe(     mode, file, args, env)

The "run" suffixes were drawn from this (which in turn are drawn from
the C library system calls.)
