What you can (and should :-) do is to define one of these six ints as a
flag saying "there are n message in the queue please call the
appropriate primitive to retrieve the contents" and buffer everything in
the VM. No need to abuse the event structure just to stick in something
that it wasn't designed to deal with ;-)
