New description:

 With a restrictive firewall that blocks traffic to localhost (or
 127.0.0.1) except for specific ports --such as the one in Tails-- it is
 not possible to run the test suite as it tries to connect to random ports
 on localhost.

 For instance:

 {{{
 tahoe debug trial --rterrors allmydata.test.test_web
 [ERROR]
     test_blacklist ... Traceback (most recent call last):
 Failure: twisted.internet.error.ConnectionRefusedError: Connection was
 refused by other side: 111: Connection refused.
 }}}
