|type ChildList = MVar [Weak Statement]|
|closeAllChildren :: ChildList -> IO ()|
Close all children. Intended to be called by the disconnect function in Connection.
There may be a potential race condition wherein a call to newSth at the same time as a call to this function may result in the new child not being closed.
|addChild :: ChildList -> Statement -> IO ()|
|Adds a new child to the existing list. Also takes care of registering a finalizer for it, to remove it from the list when possible.|
