Comment:

 I'm fine with any range of ports or addresses, btw.  Also don't mind ::1,
 though I do wonder if we want to be able to run this on non-v6 machine (if
 not, then all is fine imo, in fact, it may be good to explicitely test v6
 as well). I was wondering, perhaps we can also default to different
 127.0.0.0/8 addresses (ie. 127.0.0.5 or whatever).

 I don't really feel like building in some unused-port-detection for this
 class of listening ports, but perhaps we can write a small tool that finds
 one (obviously, such a setup would be subject to race conditions if other
 applications steal it between the finding and the running of the tests),
 but even for that I wonder if it's worth the trouble.

 I do worry about that loop; but not sure how it can be prevented if it is
 talking to a totally different application.

 Anyway, I think this branch is fine to merge as an interim solution.
