Turns out that a number of really old starkits use a convention which  
is no longer supported.  It's a VFS <-> MK mapping detail and has  
been obsolete for at least 3 years - it actually stems from the  
"scripted documents" era.

I found four starkits in sdarchive which were still using this  
convention:
	slidem, tinyba, tinytask, and tinyticker

I've changed them all manually, as shown in the transcript below:

   $ tclkit
   % mk::file open db slidem.kit
   db
   % mk::get db.dirs!0
   name <root> parent 0
   % mk::set db.dirs!0 parent -1
   db.dirs!0
   % ^D
   $

The gory details: with parent 0, sdx enters an infinite loop while  
recursing through the VFS.  The 2006-02-27 change in TclVFS's  
probably caused this - i.e. it makes SDX and any other VFS traversal  
code using it run away with those obsolete "parent = 0" files.

Thanks for letting me know about this.
