   We're going to need to pass a PID, or perhaps some new representation
   of a execution context, to a lot of code functions that don't allready
   have such an argument.  It is not clear to me that adding such an
   argument "because it will be needed" is correct, considering that the
   design has not yet started.  The truth is we don't know "what" will be
   needed, so we'll have to revisit this function (among many others)
   down the line anyway.

I agree with J.T. here.
