Detailed Description

Thread Handler holds array of Go4Thread Objects; each Go4Thread handles one TThread and Mutex, Condition... knows threadmanager instance that owns the handler (that owns the task connector which owns the thread handler, respectively) this threadmanager instance pointer is given to each thread and runnable on creation, thus each thread can acces its manager methods by threadmanager pointer
