That's better (for some definition of the word), but it still doesn't guarantee
you avoid races. The fact that the port is free at this point doesn't guarantee
the port will still be free when the lldb-server attempts to use it. When
running the test suite, you can have a hundred of tests attempting to allocate
ports in parallel, so it's just a matter of time before something collides.
What you really want is for lldb-server to allocate the port and let the test
suite know which port it has chosen without closing it in between (that's what
the code I pointed you to does).
