> These functions do not use the mutex. the sets can be change the underlying
> tree upon insertion. Since flow cannot be guaranteed we should use the mutex
> here ( i.e. it can be called in any order since it is public ).
> add and remove connection call this function and lock the mutex themselves.
> An alternative might be to use a recursive mutex or dramatically reduce the
> critical section in add/remove connection. This appears more desirable.
