You are right, the code doesn't work because Component::Method1 is a 
template. Something like

 typedef boost::function< void() > handler_type;
 handler_type handler = boost::bind( &DPC::Print1, &x, 2 );
 async_wait( boost::bind( &Component::Method1<handler_type>, &y, 10, 
handler ) );

should work, but doesn't, under MSVC 7.1 at least. MSVC 8.0 eats it, though.

 typedef boost::function< void() > handler_type;
 handler_type handler = boost::bind( &DPC::Print1, &x, 2 );
 void (Component::*pmf) (int, handler_type) = &Component::Method1;
 async_wait( boost::bind( pmf, &y, 10, handler ) );

works under MSVC 7.1, but is too unwieldy.
