 // TestBrowserThreadBundle is a convenience class for creating a set of
 // TestBrowserThreads, a blocking pool, and a task scheduler in unit tests. For
 // most tests, it is sufficient to just instantiate the TestBrowserThreadBundle
 // as a member variable. It is a good idea to put the TestBrowserThreadBundle as
 // the first member variable in test classes, so it is destroyed last, and the
 // test threads always exist from the perspective of other classes.
 //
 // By default, all of the created TestBrowserThreads and the task scheduler will
 // be backed by a single shared MessageLoop. If a test truly needs separate
 // threads, it can do so by passing the appropriate combination of option values
 // during the TestBrowserThreadBundle construction.
 //
 // To synchronously run tasks posted to task scheduler or to TestBrowserThreads
 // that use the shared MessageLoop, call RunLoop::Run/RunUntilIdle() on the
 // thread where the TestBrowserThreadBundle lives. The destructor of
 // TestBrowserThreadBundle runs remaining TestBrowserThreads tasks, remaining
 // blocking pool tasks, and remaining BLOCK_SHUTDOWN task scheduler tasks.
 //
 // If a test needs a MessageLoopForIO on the main thread, it should use the
 // IO_MAINLOOP option. This also allows task scheduler tasks to use
 // FileDescriptorWatcher. Most of the time, IO_MAINLOOP avoids needing to use a
 // REAL_IO_THREAD.
 //
 // For some tests it is important to emulate real browser startup. During real
-// browser startup some initialization is done (e.g. creation of thread objects)
-// between creating the main thread message loop, which is bound to the existing
-// main thread, and starting the other threads. Passing DONT_START_THREADS to
-// constructor will delay staring these other threads until the test explicitly
-// calls Start().
+// browser startup, the main MessageLoop is created before other threads.
+// Passing DONT_CREATE_THREADS to constructor will delay creating other threads
+// until the test explicitly calls CreateThreads().
 //
-// DONT_START_THREADS should only be used when the options specify at least
+// DONT_CREATE_THREADS should only be used when the options specify at least
 // one real thread other than the main thread.
