This value is a previously-computed hash of the key, so it makes sense to bundle it with the key inside the guard, since the guard will need it on completion anyway.
…ercote Rename the query system's `JobOwner` to `ActiveJobGuard`, and include `key_hash` `JobOwner` appears to have had more responsibilities in the past, but nowadays it's just a stack-guard object used by `execute_job` to poison the query state for the current key if some inner part of query execution panics. The new name and comments should hopefully be clearer about its (limited) role. I have also included a follow-up change that stores both the key and its previously-computed hash in the guard, instead of just the key. This avoids having to pass the key to `complete`, and avoids having to recompute the hash in `drop`. r? nnethercote (or compiler)
