While I'm not sure whether parsing long sys file lines takes much cpu, I
do know that batching and compressing for downstream leaves does.  For this
reason we run a group batch (thanks to csg@pyramid) which allows us to batch
once for most of our leaves.  It saves a lot of cpu and spool space.  It
doesn't lend itself to selective batching, though, and it means you'll have
to add another sys file line if you want ihave/sendme.
