Hmm, I'll have to think about how this should actually work.  The problem 
in this case is that making things work one way breaks them another way.
But splices and sub-DAGs should probably work as similarly as possible, so 
maybe this could be considered a bug.  I'm confident, though, that it's 
worked this way for a long time -- I guess it could be considered more of 
a design bug than an implementation bug.

If you use SUBDAG EXTERNALs instead of splices, though, things should work 
the way you want.  (Is there any reason you really need to use splices 
rather than sub-DAGs?)  (E.g., throttling?)
