 // Unfortunately, this needs to be Windows only for now. Even though this test
 // is meant to exercise code that is for Windows only, it is a good general
 // canary in the coal mine for problems related to early shutdown (aborted
 // startup). Sadly, it times out on platforms other than Windows, so I can't
 // enable it for those platforms at the moment. I hope one day our test harness
 // will be improved to support this so we can get coverage on other platforms.

 // By passing kTryChromeAgain with a magic value > 10000 we cause Chrome
 // to exit fairly early.
 // Quickly exiting Chrome (regardless of this particular flag -- it
 // doesn't do anything other than cause Chrome to quit on startup on
 // non-Windows) was a cause of crashes (see bug 34799 for example) so
 // this is a useful test of the startup/quick-shutdown cycle.

 // Note to Sheriffs: This test (as you can read about above) simply causes
 // Chrome to shutdown early, and, as such, has proven to be pretty good at
 // finding problems related to shutdown. Sheriff, before marking this test as
 // disabled, please consider that this test is meant to catch when people
 // introduce changes that crash Chrome during shutdown and disabling this test
 // and moving on removes a safeguard meant to avoid an even bigger thorny mess
 // to untangle much later down the line. Disabling the test also means that the
 // people who get blamed are not the ones that introduced the crash (in other
 // words, don't shoot the messenger). So, please help us avoid additional
 // shutdown crashes from creeping in, by doing the following:
 // Run chrome.exe --try-chrome-again=10001. This is all that the test does and
 // should be enough to trigger the failure. If it is a crash (most likely) then
 // look at the callstack and see if any of the components have been touched
 // recently. Look at recent changes to startup, such as any change to
 // ChromeBrowserMainParts, specifically PreCreateThreadsImpl and see if someone
 // has been reordering code blocks for startup. Try reverting any suspicious
 // changes to see if it affects the test. History shows that waiting until later
 // only makes the problem worse.
