The annotation functions would need to add functions to that hook when
they are run.  Maybe this is a good solution, but I'm not sure.

Another idea: allow a new type of return value for annotation functions,
and use this to keep track of buffers to be killed.  For example, allow
annotation functions to return (FUN1 . FUN2), where FUN1 and FUN2 are
lambda functions.  Then FUN1 is called during annotation, and FUN2 is
called after other annotations have taken place.
