> The way parallelism is handled in TwitterUserInformationProvider can cause the provider
to stall when more threads are created than the size of the execution service queue which
is hard-coded to twenty.
> The size of the execution service queue should equal the number of threads to ensure
that startStream() does not block trying to add more threads, because until startStream()
completes the local runtime does not poll readCurrent().
