  Log:
  MFC: handle concurrent attempts to abort the same transfer, by
  sleeping if necessary and prioritising normal abort requests over
  timeouts. This fixes crashes that occur when a transfer is aborted
  after it has timed out but before the timeout processing completes,
  as was quite frequently seen when lpd was printing to a USB printer.
