Comment(by asn):

 {{{
 < asn_> I admit I don't understand the issue well enough to propose a good
 fix.
 < oftc_must_be_destroyed> no good fix, only kludge is to append to queue
 < oftc_must_be_destroyed> but then need to change logic of circ free
 < oftc_must_be_destroyed> circuit_close_all_marked
 < oftc_must_be_destroyed> so i didin't free circ till any cells on queue
 < oftc_must_be_destroyed> or refactor code so no non queued cells at all
 < oftc_must_be_destroyed> but then padding will wait queue
 < oftc_must_be_destroyed> then it will lead non padding
 < oftc_must_be_destroyed> why need padding that arrives after several
 hours
 < oftc_must_be_destroyed> and about destroy
 < oftc_must_be_destroyed> why it need to clear cell queue if destroy
 arrived
 < oftc_must_be_destroyed> cell queues design failure
