Two other reasons:

1. It would allow HURD-NG to directly use the existing Coyotos
framework, which would be a big boost.

2. When the implementation is handled this way, it becomes a very simple
matter to #ifdef-out the createYield operation, while retaining a great
deal of code compatibility.

The discussion at hand does not raise any objection to the constructor
as a means of performing process construction. It is only the opacity
issue that is a concern.
