docs: <p>
  Remove a recoverable unit section from the recoverable unit.
  </p>
  
  <p>
  The recoverable unit section is no longer considered valid after this
  call. The client service must not invoke any further methods on it.
  </p>
  
  <p>
  The RLS will remove the recoverable unit section from its "in memory" copy of
  the recovery log and write (but not force) a record of this deletion to
  underlying recovery log. This means that in the event of a server failure,
  this recoverable unit section may be reconstructed during recovery processing
  and client services must be able to cope with this. Any subsequent force
  operation will ensure that this deletion record is persisted to disk and any
  subsequent keypoint operation will remove all reference to the recoverable
  unit from the recovery log.
  </p>
  
  <p>
  This method must not be invoked whilst an unclosed LogCursor is held for the
  recoverable unit sections in this recoverable unit. The
  <code>LogCursor.remove</code> method should be used instead.
  </p>
  
  @param identity The identity of the target recoverable unit section.
  
  @exception InvalidRecoverableUnitSectionException The recoverable unit section
  does not exist.
  @exception InternalLogException An unexpected error has occured.
