4.  The design claims:

template<typename Mutex>
class rw_mutex
{
   //...
private:
   Mutex m;
};

But the prototype implementation is:
class rw_mutex
{
   //...
private:
   boost::mutex m;
};

I like the idea of using Mutex as a template argument, because it 
lets us push the recursive vs. checked vs. unspecified mutex locking 
behavior out of the design and implementation of rw_mutex, and I 
don't have to hand-code recursive_rw_mutex....

BUT, if I do that, then my entire implementation of rw_mutex has to 
be in the header file for rw_mutex.hpp, since many compilers/linkers 
don't support seperate compilation of template class 
implementations...

Any opinions on the tradeoffs?  Should we just give in and write 
recursive_rw_mutex, (and recursive_try_rw_mutex, and 
recursive_timed_rw_mutex) ? 

Thanks,
