Comment(by mikeperry):
Looking deeper into this, those first two purposes (6 and 5) so far all
appear to have has_opened=1. This appears to cause circuit_expire_building
to select the cannibalized_cutoff for them, which is *half* of the current
circuit build timeout. For the record, they also have desired_path_len=4,
but since has_opened=1, they don't get assinged the fourhop_cutoff
timeout.
Purpose 9 has the same has_opened -> cannibalized problem, but only has a
desired_path_len of 3.
I am tempted to simply remove the has_opened -> cannibalized timeout
differentiation, and simply use the desired_path_len for cutoff selection.
