 < oftc_must_be_destroyed> I found some nice stucking for streams
 < oftc_must_be_destroyed> onnection_ap_process_end_not_open() counts every
 reasons without excpetion assume it will translated to socks answer as
 failure code. but!
 < oftc_must_be_destroyed> END_STREAM_REASON_DONE translated to
 SOCKS5_SUCCEEDED
 < oftc_must_be_destroyed> did you got it?
 < oftc_must_be_destroyed> exit closed conn but socks client assume it
 successly open.
 < oftc_must_be_destroyed> stuck
 < oftc_must_be_destroyed> connection_ap_process_end_not_open should to
 count END_STREAM_REASON_DONE specificaly and modify it to some reason
 about error.
 < asn_> oftc_must_be_destroyed: IIUC connection_ap_process_end_not_open()
 must consider END_STREAM_REASON_DONE as an error, but it doesn't.
 < asn_> oftc_must_be_destroyed: and instead of killing the SOCKS stream,
 it's marked as established.
 < asn_> oftc_must_be_destroyed: or something.
 < oftc_must_be_destroyed> well it marking for close anyway
 < oftc_must_be_destroyed> but client sees success
 < oftc_must_be_destroyed> socks client
 < oftc_must_be_destroyed> and nexit conn closed. suddenly
 < oftc_must_be_destroyed> exit answer with END_STREAM_REASON_DONE if eof
 or EPIPE
 < oftc_must_be_destroyed> it's better to count END_STREAM_REASON_DONE as
 END_STREAM_REASON_MISC while process it by
 connection_ap_process_end_not_open
