I assume you mean that the time each tasklet will expect to wait is O(n).

This limitation really has nothing to do with tasklets -- it's simply
a question of how much load your server can handle.  When someone says
"tasklets are cheap", they mean that tasklets add little overhead --
not that the work will somehow get done faster.
