// gc note: transient errors in distributed RMs may cause values to disappear in one scan and then reappear later.
// under the current model we'll recover Xids only if they stick around for enough consecutive scans to
// span the safely interval. In the unlikely event that causes problems, we'll need to postpone gc for a given
// interval and take care to include only Xids seen in the most recent scan when returning candidates for recovery.
