// There are various situations where the browser process should continue to
// run after the last browser window has closed - the Mac always continues
// running until the user explicitly quits, and on Windows/Linux the application
// should not shutdown when the last browser window closes if there are any
// BackgroundContents running.
// When the user explicitly chooses to shutdown the app (via the "Exit" or
// "Quit" menu items) BrowserList will call SetTryingToQuit() to tell itself to
// initiate a shutdown when the last window closes.
// If the quit is aborted, then the flag should be reset.
// This is a low-level mutator; in general, don't call SetTryingToQuit(true),
// except from appropriate places in BrowserList. To quit, use usual means,
// e.g., using |chrome_browser_application_mac::Terminate()| on the Mac, or
// |BrowserList::CloseAllWindowsAndExit()| on other platforms. To stop quitting,
// use |chrome_browser_application_mac::CancelTerminate()| on the Mac; other
// platforms can call SetTryingToQuit(false) directly.

// This is true on X during an END_SESSION, when we can no longer depend
// on the X server to be running. As a result we don't explicitly close the
// browser windows, which can lead to conditions which would fail checks.
