Oops -- I'll fix that up.

The idea behind the "Internal" tag is to tell users, "Unless you've been 
manually messing around with xenstore removing nodes, this is definitely 
not your fault."
I guess normally an ASSERT communicates that pretty well, but I guess 
I'm used to ASSERTs that disappear when DEBUG is turned off. :-)  Is 
that not the case for libxl?
