    I took a quick look at this. I am wondering if this actually needs an extra timer service for retries.
    
    Can this be solved without a timer? The failures could be detected in the `invoke(...)` method, and the retry done directly there (with some minimal backoff or so). 
    
    Triggering asynchronous timers is very complex and easily creates leaks, races, or leftover work / tasks at shutdown.
