Backporting the TCP Loopack fast path (Windows) improvement to JDK 8 - JDK-8060170

[Martin Sawicki (MS OPEN TECH)]

Sean, I do not have a strong reason to argue for pushing these into u40. 
Thank you for the update. 
Best regards
Martin

Martin,

both fixes have now been integrated into jdk8u-dev.  You'll see backports created off the master bug :

https://bugs.openjdk.java.net/browse/JDK-8060170
https://bugs.openjdk.java.net/browse/JDK-8064407

Since we're past the rampdown 2 stage for 8u40 [1], the fixes haven't made 8u40 release. If you feel that these fixes are important for 8u40, I can work with you in getting a phase 2 approval request submitted [2].

regards,
Sean.
