With the default QoS for send window size, a reliable writer using KEEP_LAST history may block on write

Note : This solution applies to RTI Data Distribution Service 4.5c. Applications that use writers with KEEP_LAST history may behave differently when built with 4.5c, compromising backward compatibility.
