The documentation for throwTo says:
throwTo does not return until the exception has been raised in the
target thread. The calling thread can thus be certain that the target
thread has received the exception. This is a useful property to know
when dealing with race conditions: eg. if there are two threads that
can kill each other, it is guaranteed that only one of the threads
will get to kill the other.
I don't see how the last sentense follows. I understood it so that the
throwTo has returned => exception has been delivered
is true, but not the reverse. If my understanding is correct, then both
exceptions could be delivered without any of throwTos returning.
Or is it true that
throwTo has returned <=> exception has been delivered
