In order to perform IO operations the copier will create futures using
efl_future_use(&pd->job, ...), which will set pd->job to NULL once the
future is destroyed. However this may lead to problems, because in some
cases the copier may be deleted at the _efl_io_copier_job() function,
which is the future's callback. Since the copier may be deleted before
the future, the area pointed by pd->job will have disappeared by the time the future
tries to set pd->job to NULL. To avoid this problem the copier must
explicily call efl_wref_del().
