* It does this by replacing System.out with a memory backed buffer, writing some log messages
* and then checking the buffer contents for the expected regexps.
*
* Note: due to the way logging is initialized, this is somewhat fragile.
* In general you can run only one such test in a given JVM without risking interference.
