 If you can run this easily, can you run it under ktruss and check what
 the arguments to the lethal rename call are? (do "ktruss -i tcl
 whatever", and it should panic right after reporting a rename syscall)
 
 if it's not that easy, I can try to set up the tcl test suite, but it
 may take a few days.
 
 (I tried to replicate the problem by making simple rename calls, using
 path constructs that might yield "" like it's tripping on, and so far
 I can't find a case that dies)
