Hi everyone,
I'm looking into adding sched_setscheduler support
to sfront (http://www.cs.berkeley.edu/~lazzaro/sa), and
had a quick question for the list --
---
If there's only one process running on SCHED_FIFO,
and the process wants to let the SCHED_OTHER processes have
a chance at running, what's the best way to do this?
Experimentally, calling usleep() with a value > 10ms does
it in practice (I assume this is > 1/HZ), but it does enforce
a minimum time delay -- is there a way to get "let SCHED_OTHER
processes that want to run run, then get back to me ASAP"
behavior?
This is basically a way for the application to let
a "control-C" in the shell that creates it to terminate it
once every few minutes, w/o having to go through the hassle
of locating the X server, window manager, xterm, and shell
and setting them all to SCHED_FIFO too.

Thanks in advance,
