it's a compatibility hack only. Threaded handlers are a different type
of flow, but often the fasteoi handler is not changed to the threaded
handler so i changed it to be a threaded handler too.
threaded handlers need a mask() + an ack(), because that's the correct
model to map them to kernel threads - threaded handlers can be delayed
for a long time if something higher-prio is preempting them.
