    All unit tests and regression tests "passed". However, in the logs, I saw TestFragmentExecutorCancel failed to cleanup properly. When I try to debug the issue, there is no problem. So it seems like there is a timing issue. I will try other means, and post an update.

> Once we enabled RPC thread offload, we saw concurrency regressions DRILL-4041 and DRILL-4057. The regressions appear to be unrelated to, but exposed by the thread offload. To simplify things, we disabled the RPC thread offload by default. This is the tracking issue to fix the underlying concurrency bug(s).
