/** This class provides an unlimited (thread-safe) cache for connections. It listens on a file descriptor and caches the input until it is fetched by the "next" or "nextWithLimit" method. The file descriptor is read by a separate thread (hence makes the application multi-threaded when necessary). All methods are thread-safe since the cache maintains its own mutex. */
