-------------------------------------

Thanks for the clarifications. I cleaned up {{isSafeForBootstrap}} and 
implemented the nits in the [latest 
commit|https://github.com/stef1927/cassandra/commit/ba9a69ea21b6cf2e70408ba62522a4a58b695e3f].

> Since CASSANDRA-7939, checkForEndpointCollision no longer catches a 
> legitimate collision. Without CASSANDRA-7939, wiping a node and starting it 
> again fails with 'A node with address %s already exists', but with it the 
> node happily enters joining state, potentially streaming from the wrong place 
> and violating consistency.
