The easiest solution would be for you to define

void my_schedule( pool & my_pool, int k )
{
  schedule( pool, boost::bind( task, k ) );
}

and then use my_schedule above (you'll need ref(my_pool) though.)

Or, you could bind &pool::schedule directly, without going via the schedule convenience wrapper:

  bind( &pool::schedule, &my_pool, protect( bind( task, _1 ) ) )
