DatagramChannelConfig setWriteSpinCount(int writeSpinCount)
ChannelConfig
WritableByteChannel.write(ByteBuffer)
returns a non-zero value.
It is similar to what a spin lock is used for in concurrency programming.
It improves memory utilization and write throughput depending on
the platform that JVM runs on. The default value is 16
