There are far more important tasks to be done...
Unused daemon pages can be swapped out (or alternatively locked into
memory), and don't have startup costs associated with a callback. I
would rather have a daemon startup and manage its little domain, than
have the kernel directly executing scripts and such.
A callback has far far more latency than a daemon sleeping on a fd,
waiting for the kernel to wake it up.
