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.
