... | Creates an instrumented thread pool that creates new threads as needed, but
will reuse previously constructed threads when they are
available. These pools will typically improve the performance
of programs that execute many short-lived asynchronous tasks.
Calls to {@code execute} will reuse previously constructed
threads if available. If no existing thread is available, a new
thread will be created and added to the pool. Threads that have
not been used for sixty seconds are terminated and removed from
the cache. Thus, a pool that remains idle for long enough will
not consume any resource. Note that pools with similar
properties but different details (for example, timeout parameters)
may be created using {@link ThreadPoolExecutor} constructors.
@param registry the {@link MetricRegistry} that will contain the metrics.
@param name the (metrics) name for this executor service, see {@link MetricRegistry#name(String, String...)}.
