 >>isn't it better to delete completed threads as soon as possible? in the
 current implementation they are not purged until a new xfrin attempt
 occurs.
 > For this, We can delete completed threads as soon as possible. but when
 we delete completed threads, it will find this thread`s fd in hash map,
 this waste time. I purged it when a new xfrin attempt occurs. This will
 not run delete, it save time. Although It will occupy some memory, but It
 is little, it`s number less than max_transfers_in. So I did so.

 >>I believe we should use select for connect and send while watching a
 shutdown event. consider, e.g., the case where a shutdown event is sent
 when the primary server is dead and connect blocks. but it's okay for me
 to leave this enhancement to another ticket (or we should rather do so)

 > I think it is better to create another ticket to solve this.

 > For the newest code, I delete connect function. For error code 0, it is
 success, so there is no exception,  And add a DEFAULT_TRANSFER_IN variable
 to remove the hardcoding.
