[LAU] Large live recrodings ?

[Kjetil S. Matheussen]

nice only controls CPU usage, not HD usage. nice can
however make programs that access the HD access the HD
a little bit less often, but it will not prevent it from
using the HD.

For example, try running "slocate -u" with nice 19
and "jack_capture -c 64" with nice -20. You'll see
that jack_capture will struggle a lot more using
this setup than if you had been running
"jack_capture -c 64" with nice 19, and not running
"slocate -u" at all.
