This looks like a pretty clean refactoring to allow further extensions with 
per-thread data.

It looks like you removed a random newline in the Thread constructor and 
another newline in the Thread class declaration.

thread_ext.cpp should only need two includes:
precompiled.hpp and thread_ext.hpp it does not reference anything in the 
Thread class.

I've verified that the code which is moved outside INCLUDE_MANAGEMENT in 
management.cpp is a clean copy.

With those small nits fixed immediately or deferred for future cleanup this 
looks good to me.
