Currently it will print this:

=== output begin ===

This binary has no thread support compiled in.
Recompile the application with a thread-driver in the program uses 
clause before other units using thread.

=== output end ===

This is the standard implementation of threading functions if no other 
thread manager is provided (TThread.Yield calls System.ThreadSwitch 
which calls TThreadManager.ThreadSwitch). Otherwise it will depend on 
the threading manager implemented... (see Nikolay's other mail)
