> Producing output from another thread will break the assumption that users who 
> use this library may have where they don't need synchronization since methods 
> like startBundle/finishBundle/processElement are all meant to be [accessed 
> from one 
> thread|https://beam.apache.org/documentation/programming-guide/#user-code-thread-compatibility]
>  and will also break similar assumptions in the system (for example 
> counters/monitoring rely on a thread local being set to pass a context object 
> around).
