What about shared interrupts? How are they going to be treated? With the
spl leaving the arena it somehow looks feasible to run one interrupt
source on two different threads if there are two pieces of hardware
attached to the same interrupt line.
>From what I understood from dfr, when switching away from an interrupt
handler it is converted into a full thread. When the second piece of
hardware fires an interrupt it could then run at the same time.
