If we decide to add this, maybe we should give the users a chance to test for this themselves ?

Procedure CheckThreadInitialize;

This way they can call this at the entry point of some externally called routines.
For windows, we'd need this 'check' procedure anyway, since there are 2 notification mechanisms.
(TLS callback and DLL_THREAD_ATTACH)
If the RTL is already initialized for this thread, it would do nothing.
