except for the unnecessary line break, this could also easily be replaced
by `new TaskEventDispatcher();` instead

> While Buffer class is used in multithreaded context it requires
> synchronisation. Now it is miss-leading/unclear and suggesting that
> RecordSerializer should take into account synchronisation of the Buffer
> that's holding. With NotThreadSafe BufferBuilder there would be clear
> separation between single-threaded writing/creating a BufferBuilder and
> multithreaded Buffer handling/retaining/recycling.
