Though I'm not a spokesperson of Rémi, I interpreted it differently.
That is - assuming join is invoked without interruption - my problem
with the shown behaviour is that the exception thrown by the
`Callable` is discarded and an ISE is thrown instead, so we are losing
the original exception which could be used for tracking the issue.
