Hmm...

Isn't that problem solved already by nice'ing a process?
I think that problem is completely solved by idprio'ing a
process...

Because:
When the NIC gets a packet for a database server, the kernel
interrupts the executing of a potential idprio'ed process and
starts the DB process... Or am I wrong?
