dead handler detector?

[Alex Tweedly]

In some circumstances, it's not "more complex", it's "impossible".
For example, something like

--  don't do this for real :-)
repeat forever
   ask "What should I do next?"
   if it = "quit" then exit repeat
   put it into tNextHandler
   do "tNextHandler"
next repeat

However, there are cases less egregious than this which can hide the 
handler name pretty thoroughly, so  you need to decide just *how* far 
dead a handler needs to be in order to remove it :-)
