I don't know anything about kernel scheduling, but experimented a
little with a QNX patched kernel.
I ran a prime generator program in MIT-Scheme, and then increased the
priority of the scheme process, thinking, naively, that it would
speed up the calculations.
The procmeter CPU meter went solid black, and I could not regain
control of the computer, which was happily computing prime numbers.
It occured to me that if you went and upped the priority of your
Apache daemon, and a CGI program began to infloop, you'd have to
reboot your server to get it back. That sort of situation could be
dangerous in some industrial environments...
