- * REVISIONS:
- * CSH 01/08-2000 Created
- * Vizzini 08-Oct-2003 Formatting, commenting, and ASSERTs

- * NOTES:
- * - Although the standard kernel-mode M.O. is to trust the caller
- * to not provide bad arguments, we have added lots of argument
- * validation to assist in the effort to get third-party binaries
- * working. It is easiest to track bugs when things break quickly
