Detailed Description

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.
