To do this completely we'll need functions to hook into the scheduler, be
able to get the kernel to vector to a device driver upon an interrupt from a
peripheral etc. and do this efficently.

We are obviously not there yet as we have to use kludgey solutions such as
the sld daemon for MiNTnet. The functionality of the sld daemon and other
such daemons should be able to be set up seemlessly using kernel callbacks
into device drivers etc. The kernel scheduler itself should be at a lower
priority than devices so that interrupts are handled as quickly as possible.
