What is MapPtrT?

It seems that the static destructors are being run after on_thread_exit for 
the main thread; that's pretty odd. I see some logic in tss.cpp that looks 
like it should handle the case of ordering/race issues between 
~thread_specific_ptr and the thread exit cleanup, but the code is too 
complicated to tell. Maybe you need to instrument tss.cpp and tss_hooks.cpp 
to see what is being called and when.
