I am working on it as time allows. After debugging this latest data 
point (running longer avoid the segfault) I certainly understand the 
problem better, but the problem keeps expanding too -- like wrong paths 
on guest side modules. It really suggests that this notion of a 
'default' guest is just wrong - too little information. We'll see.
