Comment (by mikeperry):

 What is the theory that makes you think this is a good idea? Raising this
 value to 5 hours will mean that clients keep otherwise unused circuits
 opened for 5 hours, which means more memory use at relays for these open
 circuits. Additionally, it means that the OR connections to the relays
 will also be held open and padded for 5 hours, resulting in bandwidth
 overhead and higher overall connection counts. As I see it, this could
 make things much, much worse.
