Yes please.

No, ideally I will be able to provide constructor arguments when I
declare my TSS object:

struct Foo
{
   Foo( const std::string &s, int i );
   //...
};

boost::thread_specific<Foo> bob( "Bob", 3 );

This would call Foo("Bob",3) to provide an initial value for bob for
every new thread, and of course would clean up when threads terminate.

I think I just did make a suggestion. ;-)
