// XPCOM-in-subprocesses depends on IPC, e.g. to init the pref

|
|
// 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
