AFAIR the TThread implementation makes use of the ThreadManager (it 
calls BeginThread and all that stuff).

Initialize is it in the BeginThread subroutine of your ThreadManager as 
it is done for all other targets that need special initialization. 
There is a global variable System.IsMultThread for exactly that 
purpose, I think.
