Review comment:
In the current `master`, if an exception is thrown in both
`shutdownAsyncThreads` **and** `operatorChain.releaseOutputs` then both
exceptions are logged/thrown.
In this PR, only the latter will be thrown.
The simplest fix is to add `if (suppressedException != null) throw
suppressedException;` before `if (operatorChain != null)` and
`mailboxProcessor.close`.
More elegant way is to add `fail-immediately` flag to
`runAndSuppressThrowable` with `true` for lines 629 and 640.
