Reset the io_service in preparation for
          a subsequent run()
          invocation.
        
void reset();
          This function must be called prior to any second or later set of invocations
          of the run(),
          run_one(),
          poll()
          or poll_one()
          functions when a previous invocation of these functions returned due to
          the io_service
          being stopped or running out of work. After a call to reset(), the io_service object's stopped()
          function will return false.
        
          This function must not be called while there are any unfinished calls to
          the run(),
          run_one(),
          poll()
          or poll_one()
          functions.
