@abliss Pull Request #196 was manually merged via @joshgord's Pull Request #222. @joshgord is working on unit tests of Exceptions getting thrown by operation in finally block. Once that's done, this issue will be closed.

Here is the test case @mattrjacobs is referring to:

    @Test
    public void testFinallyError() {
        Action0 errorAction = new Action0() {

            @Override
            public void call() {
                throw new RuntimeException("boo");
            }
        };

        try {
            Observable.create(finallyDo((Observable.toObservable("foo")), errorAction)).subscribe(aObserver);
            fail();
        } catch (Exception e) {
            // pass
        }
    }

We will address the exception handling in another issue and will close this one out now. Thank you very much @abliss for you contribution!!
