Many relays breaks usability for users by trying so small time of syn packet that connection timeout is very low if relay overloaded and syn was lost. Tor client have no ability to retry with another circuit if reason for end cell is timeout or refused. By default Tor can to retry only if no answer for 10 (15) seconds or some end reasons.

Torflow should to test exit relays if they answers timeout faster than after 15 seconds or refuses for known working host.

Relays that overtuned or overfirewalled still usefull as non-exit relays but should be marked as BadExits if stable Tor client version can't to retry.
