This task is responsible for pushing data to the hidden region. It is executed in a single
thread from newSingleThreadScheduledExecutor; Only one thread will be responsible
for pushing the data to the hidden region.

(Note however that if this single thread terminates due to a failure during execution prior to
shutdown, a new one will take its place if needed to execute subsequent tasks.) Tasks are
guaranteed to execute sequentially, and no more than one task will be active at any given time.
Unlike the otherwise equivalent <tt>newScheduledThreadPool(1)</tt> the returned executor is
guaranteed not to be reconfigurable to use additional threads.
