> Addresses Jdk 8288899 : java/util/concurrent/ExecutorService/CloseTest.java 
> failed with "InterruptedException: sleep interrupted" and related issues.
> 
> This is a major ForkJoin update (and hard to review -- sorry) that finally 
> addresses incompatibilities between ExecutorService and ForkJoinPool (which 
> claims to implement it), with the goal of avoiding continuing bug reports and 
> incompatibilities. Doing this required reworking internal control to use 
> phaser/seqlock-style versioning schemes (affecting nearly every method) that 
> ensure consistent data structures and actions without requiring global 
> synchronization or locking on every task execution that would massively 
> degrade performance. The previous lack of a solution to this was the main 
> reason for these incompatibilities.
