@short implement a transaction manager to support non breakable interface methods
@descr Use it to support non breakable interface methods without using any thread
synchronization like e.g. mutex, rw-lock!
That protect your code against wrong calls at wrong time ... e.g. calls after disposing an object!
Use combination of EExceptionMode and ERejectReason to detect rejected requests
and react for it. You can enable automatically throwing of exceptions too.
