My vague memory is that Trond said something to the affect of "fl_notify
is there, let's use it rather than adding yet another callback."

But our new usage of fl_notify does requires slightly different
arguments and returns, and is used in a subtly different case.  So I
wouldn't object to a new callback.  Trond?
