It means that qmail-send alternates between spawning jobs and
processing incoming mail. If mail arrives too quickly, the todo
section of the queue can create very large directories (because todo
is not a hashed tree of directories). Once qmail-send gets more than
1,000 (or thereabouts -- it depends on what filesystem you're using)
todo files, it can't recover, and the only help is to turn off
incoming mail.

Just for incoming mail.
