-------------------------------------------------+-------------------------
 Dynamic loading a dll that creates a simple thread group and then
 unloading the dll will cause the application to hang on
 thread_group::join_all.

 This happens both if we:

 Clean up the thread_group on DllMain::DLL_PROCESS_DETACH or if we have a
 global object representing the thread_group and the clean up is invoked on
 that object's destructor.

 We'll attach a simple solution where this problem can be reproduced.
