Actually this problem is fixed in Windows 98. I had to tune it a bit so
that maintenance jobs wouldn't kick in during a CD write, so I put heavy
jobs on a 240 minute console idle required instead of the default 10 minutes
(after throwing a couple of CDs in the bin from buffer overruns). The
Scheduled Tasks thing has a properties sheet including rules like "require
console idle [XXX] minutes". Maybe cron could use some of these rules and
properties, some of them don't translate into anything sensible for Linux
though.
However this is somewhere "cron" might need to be improved, not the kernel.
ie: don't run jobs marked as intensive while burning a CD -- I'm not sure
how to sense burning a CD and playing games and so on, load average gives you
some information, idle time might be measurable in some way, ...
Maybe a cron daemon with a syntax which lets you specify that when the load
avg is over X (say, 0.95) re-check the load average every Y minutes up to a
maximum of Z minutes (at which time the job is either run or thrown away).
Of course making CD burning and console games run with a priority and
performance unaffected by other jobs which might come up while they are
running is a much more ideal situation.
