Hello all!

I have an updated patch for https://bugs.openjdk.java.net/browse/JDK-8171181 at http://cr.openjdk.java.net/~kkharbas/8171181/webrev.05
I have lost the old email chain so had to start a fresh one. The archived conversation can be found at - http://mail.openjdk.java.net/pipermail/hotspot-runtime-dev/2017-March/022733.html

1.       I have worked on all the comments and fixed the bugs. Mainly bugs fixed are related to sigprocmask() and changed the implementation such that 'fd' is not passed all the way down the call stack. Thus minimizing function signature changes.

2.       Patch supports all OS'es. Consolidated all Posix compliant OS's implementation in os_posix.cpp.

3.       The patch is tested on Windows and Linux. Working on testing it on other OS'es.

Let me know if this version looks clean and correct.
