I'm not sure about other platforms, but don't Linux(2.6), FreeBSD Plan9
(from reading man proc), and Windows support [soft] realtime within the OS
out-of-the-box? I know you can get a POSIX 1003.1b implementation to bring
your OS (at least those with source available) up to realtime specs. Perhaps
one could [re]build the platform emu with a flag setting specifying whether
or not they have realtime support (Windows, Plan9 or POSIX)???

I can easily see how this could present a challenge on non-native platforms
even if the hosting platform had real-time support, but I can also see great
benefits to having realtime capabilities within native Inferno. Are there no
plans to support proc (perhaps with different results depending on host w/o
realtime support vs. native Inferno or host with realtime support)?

Thanks for the clarification, I had recently read man prog but was hoping
the realtime features of proc (i.e., period, deadline, cost, yieldonblock,
etc.) where somewhere hidden within Inferno.

Thanks,
