smart_ptr thread safety

I was wondering what the current thinking is on making the smart pointers
threadsafe.  Is it likely that Boost.Threads would be used for this purpose?

If so (or if not), how efficient is a threadsafe implementation likely to
be?  I've noticed that gcc's basic_string is reference-counted and uses
inlined assembly to access atomic instructions.  Is that a strategy boost is
likely to follow?
