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.
