Hi,
    Is it advisable to use the shared_ptr<> class in a multithreaded 
environment where there is a possibility of it being passed across 
thread boundaries? I initially got the CountedPtr<> class from "The 
C++ Standard Library: A Tutorial and Reference" by Nicolai M.
Josuttis (p. 222) and extended it to be thread-safe by adding a 
mutex-lock (which is new'ed along with count) on the reference count. 
But I am not sure if this is a good idea. Any thoughts or suggestions 
on this?

Thanks in advance,
Sudheer Tumuluru
