It can, and I've checked in the change.

There was already an add_thread_exit() that did this; at_thread_exit is 
a better name, so I've just checked in the changes to use it. Functions 
passed to at_thread_exit() are what get called by on_thread_exit(). The 
dll version of Boost.Threads on Win32 calls on_thread_exit() 
automatically when a thread exits; in static builds of Boost.Threads, 
the user is responsible for calling on_thread_exit(), though hopefully 
this will change in a future Boost.Threads release.

Were you suggesting that at_thread_exit be publically exposed as a 
feature of Boost.Threads on all platforms?
