-// used to integrate the CEF message loop into an existing application message
-// loop. Care must be taken to balance performance against excessive CPU usage.
-// This function should only be called on the main application thread and only
-// if CefInitialize() is called with a CefSettings.multi_threaded_message_loop
-// value of false. This function will not block.
+// provided for cases where the CEF message loop must be integrated into an
+// existing application message loop. Use of this function is not recommended
+// for most users; use either the CefRunMessageLoop() function or
+// CefSettings.multi_threaded_message_loop if possible. When using this function
+// care must be taken to balance performance against excessive CPU usage. It is
+// recommended to enable the CefSettings.external_message_pump option when using
+// this function so that CefBrowserProcessHandler::OnScheduleMessagePumpWork()
+// callbacks can facilitate the scheduling process. This function should only be
+// called on the main application thread and only if CefInitialize() is called
+// with a CefSettings.multi_threaded_message_loop value of false. This function
+// will not block.
