That should be normal business; I rather meant things like the
three large bzip2 processes running all day for backup purposes

I found that it's often counter productive to use compression;
however, most times small levels are more pratical, so I'd suggest
you try -z1.

Not that I know... it usually sleeps while waiting for file i/o.
