[Anton Nashatyrev]

Hello,
    could you please review the following fix:
fix: http://cr.openjdk.java.net/~anashaty/8080504/webrev.00/ 
<http://cr.openjdk.java.net/%7Eanashaty/8080504/webrev.00/>
bug: https://bugs.openjdk.java.net/browse/JDK-8080504

    Problem: under MacOS X the realSync() may hang under some 
circumstances.

    Fix:  make the  Java_sun_lwawt_macosx_LWCToolkit_nativeSyncQueue 
method respecting timeout argument

Thanks!
Anton.
