I started passing the servers into the fake session in order to identify the
session for tests.

ready_ports()?

[Taylor Brandstetter, 2016/05/06 03:53:34]

An underscore name implies it's a trivial method. Since it's a pure virtual
method, it's not guaranteed that the subclass's implementation is trivial. For
BasicPortAllocator, it isn't.

[pthatcher1, 2016/05/05 21:51:24]

candidates()?

[Taylor Brandstetter, 2016/05/06 03:53:34]

See above. I called it ReadyCandidates so that we have
SignalPortReady/ReadyPorts and SignalCandidatesReady/ReadyCandidates. Though I'd
be fine with changing it to just Candidates, since there's a difference between
a Port and a ready Port, but the same isn't true for Candidates.
