Sorry, that was rather impolite of me.  Now I've looked back through the archives I 
see that
Malcolm has tried this and found it difficult for good reason.  All the same I don't
see how it can be avoided.  In Foogle-land they can't know anything about when Haskell 
is
running a garbage collection or not, and of course Foogle might be running various 
concurrent
threads (just like Haskell), so if you are going to say that Foogle is never to call a
Haskell function during a Haskell garbage collection, I don't see how Foogle is to 
call Haskell
at all.
