I'm still missing something. Why does a process that isn't doing anything
on the filesystem still freezing? My disks are DMA, so there shouldn't be
any tim ethat the kernel is busy-waiting for a seek, right? You explained
why the I/O from one process can totally destroy the I/O bandwidth of the
other, thank you :), but I don't see how that relates to the other part
of this problem.
