The return value could be compared against
	ResultCancelled = 2,
        ResultContinue = 0,
        ResultFailed = 1
members of the acquire class.

We could do this kind of check automatically in apt.Cache and
raise an error if it is ResultFailed. The exception won't include
information about which item failed as this information is not
available from Update(). Something like this:

        if res == 2:
            raise FetchCancelledException()
        elif res == 1:
            raise FetchFailedException()
	else:
	    return res

The question remains whether this would break any other
package.
