/**
 * This class is used to cleanup any remaining data that may be on a KeepAliveStream
 * so that the connection can be cached in the KeepAliveCache.
 * Instances of this class can be used as a FIFO queue for KeepAliveCleanerEntry objects.
 * Executing this Runnable removes each KeepAliveCleanerEntry from the Queue, reads
 * the reamining bytes on its KeepAliveStream, and if successful puts the connection in
 * the KeepAliveCache.
