/**
*   This timer is used to protect the Go4 threads against
*   the CINT main application when go4 is running as cint
*   server. Go4 thread activities that acquire the Go4 main mutex
*   are only allowed within a small time window inside the
*   Notify of this timer. Besides this, the root application will
*   hold the main mutex completely, thus avoiding go4 threads
*   to interfere with root system. Note: this mechanism is the
*   complement to the threadmanager application blocking mode,
*   meant to block the root application and allow the threads
*   everything.
