    // This routine, in Windows, does a lot of what Init does, but in a radically
    // different way.
    //
    // In Windows, because CSRSS's threads have TIF_CSRSSTHREAD set (we have this
    // flag in ROS but not sure if we use it), the xxxClientThreadSetup callback
    // isn't made when CSRSS first loads WINSRV.DLL (which loads USER32.DLL).
    //
    // However, all the other calls are made as normal, and WINSRV.DLL loads
    // USER32.dll, the DllMain runs, and eventually the first NtUser system call is
    // made which initializes Win32k (and initializes the thread, but as mentioned
    // above, the thread is marked as TIF_CSRSSTHREAD).
    //
    // In the DllMain of User32, there is also a CsrClientConnectToServer call to
    // server 2 (winsrv). When this is done from CSRSS, the "InServer" flag is set,
    // so user32 will remember that it's running inside of CSRSS. Also, another
    // flag, called "FirstThread" is manually set by DllMain.
    //
    // Then, WINSRV finishes loading, and CSRSRV starts the API thread/loop. This
    // code then calls CsrConnectToUser, which calls... ClientThreadStartup. Now
    // this routine detects that it's in the server process, which means it's CSRSS
    // and that the callback never happened. It does some first-time-Win32k connection
    // initialization and caches a bunch of things -- if it's the first thread. It also
    // acquires a critical section to initialize GDI -- and then resets the first thread
    // flag.
    //
    // For now, we'll do none of this, but to support Windows' CSRSRV.DLL which calls
    // CsrConnectToUser, we'll pretend we "did something" here. Then the rest will
    // continue as normal.
    //
