Commit message

Get the port at function-call time, instead of storing a port at
start-time and giving that back. The info can be stale, the old
way.

See test run below. The error I get on any branch and even trunk, and I have no idea if it's because something is misconfigured on my system. What's worrying is that it seems the automatic starter seems to start several couchdb instances, which is bad. It does seem that there is more than one instance running after this test:
