#5380: clients that never restart never drop old guards
------------------------+---------------------------------------------------
Reporter: arma | Owner:
Type: defect | Status: new
Priority: major | Milestone: Tor: 0.2.2.x-final
Component: Tor Client | Version:
Keywords: | Parent:
Points: | Actualpoints:
------------------------+---------------------------------------------------
When we get a consensus we check whether to drop guards that have been
down long enough.
But we only compare chosen_on_date to now when we're loading the state
file, which we only do at start.
So if the Tor client stays running for more than a month or two, its guard
behavior deviates from normal.
Discovered while talking to Tariq about his guard simulation attack graphs
and trying to puzzle through his unintuitive results.
