Description of problem:

Looking at the code snippet at line 198, the wg.Add(1) should be moved closer to the function it is waiting for (line 226).

Having another function in between that could exit could leave the controller in a state where it will be waiting for a defer that can never occur, meaning that the controller will never terminate.
