For reference: CPython code comments showing that this may be an anticipated problem: http://hg.python.org/cpython/file/0830670a9d9d/Lib/test/support/__init__.py#l562 An example of another project that seems to have tackled this problem in the way neologix suggests: http://openvswitch.org/pipermail/dev/2013-April/026430.html I am inclined to frame this issue as a choice between LBYL (try to predict, subject to the race, whether a port will be available) and EAFP (blindly try a few random high ports before inferring failure).
