This is indeed very problematic, I worked on ONVIF test suite 3 years ago, in some failing test cases, the tcp socket can never die in time, it failed the certification as a whole as all the following unit test cases can not continue. All those immediately-kill-tcp-socket or socket-port-reuse can not help, at least not reliably.
