Linked Futures can result in a BinaryPrivateSemaphore beeing signaled twice
Since !120 (merged) I observe that the echo server benchmark does not terminate.
I suspect the EchoClient because the server does work with the rust echo client and accepts new connections.
After reverting afafc707 the benchmark works again therefore I am quite sure that the issue must be somewhere in !120 (merged).
