Routine Description:

    This function is called whenever a Win32 process is created or deleted.
    Creattion occurs when the calling process calls NtConvertToGuiThread.

    Deletion occurs during PspExitthread processing for the last thread in
    a process.

Arguments:

    Process - Supplies the address of the W32PROCESS to initialize

    Initialize - Supplies a boolean value that is true if the process
        is being created

Return Value:

    TBD

Routine Description:

    This function is called whenever a Win32 Thread is initialized,

    Initialization occurs when the calling thread calls NtConvertToGuiThread.

     PspThreadDelete processing.

Arguments:

    Thread - Supplies the address of the W32THREAD object

    CalloutType - Supplies the callout type


Return Value:
