The documentation for AsyncInvoker states that it owns the lifetime of calls, and when its destructor is called, all in-flight calls are cancelled or finish executing. The "cancelled" part is working, but if a call is in the middle of executing, the destructor does *not* wait. This is fixed by keeping a count of pending invocations, which is decremented when a call is either cleared from a message queue or finishes executing.
