- Ah yes (deep breath of fresh air)--this is exactly what we learned in
- our File Structures class. This is exactly what you should do!

- Aaaaaaaaahhhh (reality slams in)--everything I learned was _useless_!
- When will we be able to heapsort without pausing during reads from
- disk? When will huge Mac database programs get to be anything but a
- joke? When will I be able to smoothly scroll my word processor while
- the Finder makes a copy of my hard disk? When will the IIfx (RIP)
- get to _use_ its DMA circuitry? When can I stop saying "but at least it
- accesses the _floppies_ asynchronously"?
-
- Alas (sobbing)--when O when will my IBM-programming friends stop
- sniggering at my _totally_synchronous_ operating system?
