On Unix, nice is exactly the answer. It's a lot more fine-grained than
what you're talking about, though. But it's the way things like
setiathome manage to run continuously without interfering with normal
usage.
If that's to fine grained for you, you could try waking up every few
minutes and checking the load average (via os.getloadavg), and only
doing work if the load average is low - say less than .5. While
running, you check the load average every couple of minutes and stop
if it rises noticably above 1 (you). The problem with this approach is
that it doesn't deal well with multiple tools doing this. I.e. - if
you run setiathome, your load average will always be above 1, so you
have to adjust your check value to take into account anything else
that might be in the background. Nice handles this automatically.
