Re: [SQU] current CVS ... diskd config args changed ...

diskd and aufs are two different approaches for making disk I/O
non-blocking. This to allow Squid to scale on higher loads. Both
sacrifice CPU usage for better latency. aufs uses POSIX threads, while
diskd uses a separate I/O process per cache_dir.
