class TThread: public TNamed


TThread

This class implements threads. A thread is an execution environment
much lighter than a process. A single process can have multiple
threads. The actual work is done via the TThreadImp class (either
TPosixThread or TWin32Thread).

 Cancellation
 there are two types of TThread cancellation:
    DEFERRED     - Cancellation only in user provided cancel-points
    ASYNCHRONOUS - In any point
    DEFERRED is more safe, it is DEFAULT.
