Comment (by exarkun):

 5. Create a private network namespace for the test suite.  This removes
 the possibility of a port collision involving unrelated activities on the
 same host.  It does not remove the possibility of a port collision of
 Tahoe-LAFS code with other Tahoe-LAFS code though.  Network namespaces are
 highly platform specific and this would likely involve three or more
 implementations of the same idea.  Also, creating network namespaces
 likely requires elevated privileges imposing a practical barrier to
 deployment.

 6. Avoid binding to IN_ADDRANY.  Instead, bind to a specific interface.
 This avoids collisions with other ports bound to different specific
 interfaces.  It doesn't avoid collisions with other ports bound to
 IN_ADDRANY.  Since most collisions are probably with IN_ADDRANY-bound
 sockets this probably doesn't help a lot.
