get the perf source working
Added the first of the perf tests
Small change to convert from Caliper to JMH.
make Scala OnCompleted Notification an object instead of a class
Merge branch 'master' of github.com:Netflix/RxJava into OnCompletedScala
ObserveOn Merge from @akarnokd:OperatorRepeat2
ObserveOn with Backpressure
Make Parallel use NewThread until Computation Fixed

See https://github.com/Netflix/RxJava/issues/713
It was causing non-deterministic behavior, random test failures and poor performance.
GroupBy Test Improvement

ObserveOn was the wrong mechanism for delaying behavior as it was relying on the buffering of observeOn.
Now using delay() to delay the group since observeOn no longer buffers.
Fast Producer / Slow Consumer Backpressure Tests for ObserveOn
Custom InterruptibleBlockingQueue for ObserveOn

Since we are blocking the producer on* notifications we need to interrupt it on unsubscribe events.
I need to do it on the data structure and not the thread as the thread could change for each onNext and that could have unexpected consequences.
Changed to use SubscribeOn instead of ObserveOn for Async Behavior

The ObserveOn operator is for moving where it executes, not making it async. SubscribeOn makes it async.
Test to prove non-blocking despite blocking onNext
