- B144: when Drive says a name is taken but nothing local holds it any more,
the rename, move or create is sent once more under the wanted name before
falling back to a conflict name. The trash that freed it could land between
Drive's answer and the check.
- B145: the park sweep no longer drops a parked create whose node row is not
written yet. It waits a minute, and keeps open files, before taking a
missing row for a deleted file. The account run's B70 check failed with
EBUSY on this.
- B146: a rename queued while an upload's read-back is on the wire is kept;
the tree no longer takes back the name Drive still had.
