    This is all well and good but you're only talking about CPU.  Disk

I/O is another story entirely.  If your WM starts doing some I/O that

you weren't aware of you may get an xrun because you couldn't access the

disk in time.  This is the reason that I kill syslogd before I record.

Granted, generally speaking you'll do OK due to the priority of your

process but disk I/O takes a certain amount of time and you can't

interrupt it once it's gone to the disk.
