Hypothesis, the interruption is caused by a timeout. I'm removing the delays

[basilevs]

The test that fails to stop, continues execution and corrupts report and result of the next one.

org.eclipse.rcptt.ecl.server.tcp.SessionRequestHandler.SessionRequestHandler(Socket, boolean) relies on socket.isClosed() to detect client shutdown (which happens on cancel), but in modern Java, socket is not closed when client shuts down if it is not actively read.
