Comment (by teor):

 Replying to [comment:42 rl1987]:
 > Not sure how to solve the problem with fixed port in integration test.

 Choose a random port between 10000-60000, and retry N times if it fails.
 (Where N is small.)

 > How much it is a problem? Do people commonly run multiple tests in
 parallel?

 Yes, particularly on automated builders, or when branches are merged
 forwards.
