Why are you radically chaging the default timeout? The commit
message does not tell anything about that change.
Why couldn't we just have two timeouts: one default and one long that
would be at least as long as the longest timeout defined in the spec?
Then we would not have to ever update LAST_CC constant, we could
actually remove it completely.
