Benedict Elliott Smith commented on CASSANDRA-17928:
----------------------------------------------------
So it is not expressly discussed in that ticket, but AFAICT there is no reason
to invoke {{Thread.stop}} in the JVMKiller. Since the real JVMKiller does not
invoke Thread.stop this cannot be a critical part of the test. So a simple
condition that is signalled by the JVMKiller, that the test waits on for some
predetermined period (perhaps 10s) to confirm the JVMKiller has been invoked
seems sufficient.
However, it might be nice to confirm with the original authors [~gzh1992n],
