> 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.
