Actually, it turned out to be a bit more complicated: I forgot to test 
whether resetting the _vtab worked. Result (as to be expected): It 
didn't. I also found out that DEALLOCATE also didn't properly reset the 
_vtab. That's now fixed (and tested for) in the attached follow up patch.

(Recall that the standard mandates that an unallocated polymorphic 
variable has the declared type.)
