I'm going to make a stab in the dark and guess that you're linking  
statically against Boost.Thread from both the main app and the DLL? If  
so, then this is the reason: the DLL cannot hook the TLS cleanup into  
the boost::thread data structure from the main app, so the cleanup  
isn't called.

If you *are* using the DLL version of Boost.Thread, then I'll have to  
investigate further.
