I guess I don't quite understand how the implementation would work.  My
understanding is that the problem is, when a package like gnome has
several depends which each in turn depend on, for example gtk+, then when
we descend into each of those we in turn descent into gtk+ thus visiting
gtk+ multiple times.  What we want to do is avoid visiting any particular
package more than once.  What I don't quite understand is how/where the
list of visited packages is stored for access by various make processes.
I thought you were suggesting keeping this information in a file in the
top packages' WRKDIR which is why I asked if this WRKDIR would be passed
down.  So I'm missing something here (probably just me).
