It seems to take almost exactly 30 seconds to cycle a primary up or down on the 32-bit Windows buildbot and the test times out after 30 seconds so this is too flaky. Change the timeout from 30 seconds to 60 seconds to buy some breathing room. Also, the comments and messages displayed by this test weren't aligned with changes that had been made to it, making the log hard to follow: fix up the comments and log messages to match what the test is actually doing.
