There's nothing wrong with some healthy paranoia :-)  But it seems
unwarranted here.  The --rri task downloads all files, then merges them
together (sorting as required), then streams them to the destination.
Between database transactions and the fact that no output is sent until
everything is completely downloaded and merged, you shouldn't have any
problems importing directly.  And if something does break you should be able
to re-import anyway right?
