In Ron Minnich's ftq README there is this:

        Plan 9 support is deprecated because nobody cared, and the
        default Plan 9 timers still suck.

Has work been done in this area? What is to be achieved?

Plan 9 timers were never very precise, although /dev/bintime might be
better now.

I'd be happy to see a forward port of ftq to Plan 9, I don't think it
would be hard.

since you touched this topic in the past and unlike me have some experience
with it:
given the current multicore hardware architecture, DMA, inter-core,
inter-socket latencies, how precise do you suppose should one try to make
timers in the first place? and how far from this are we?
