Nope.  SEnd the oldest data first.  Maybe don't send it all at once - but 
record into rrd from your queue oldest first.

If the data is too much, you might consider a max amount that you'll keep 
in the queue, and if you queue more, drop older entries (creating a gap) 
but once your system is back online and catches up you'll have recent 
history.
