// that's unaware of MessagePump. That's all rather suboptimal,
// but oddly enough not a problem... usually.
//
// The problem with this setup comes during startup.
// XPCOM-in-subprocesses depends on IPC, e.g. to init the pref
// service, so we have to init IPC first. But, IPC also
// indirectly kinda-depends on XPCOM, because MessagePump
// schedules work from off-main threads (e.g. IO thread) by
// using NS_DispatchToMainThread(). If the IO thread receives a
// Message from the parent before nsThreadManager is
// initialized, then DispatchToMainThread() will fail, although
// MessagePump will remember the task. This race condition
// isn't a problem when appShell->Run() ends up in
// MessagePump::Run(), because MessagePump will immediate see it
// has work to do. It *is* a problem when we end up in [NSApp
// run], because it's not aware that MessagePump has work that
// needs to be processed; that was supposed to be signaled by
// nsIRunnable(s).
//
// So instead of hacking Cocoa nsAppShell or rewriting the
