 * Fool OS System Calls
 * ====================
 *
 * This is THE way for user programms to communicate with the kernel.
 *
 * The kernel exhibits a set of a few posix-style calls and some other
 * non-standard foolish calls invented by myself. 
 *
 * TODO: DOCUMENT each call! 
 *       reentrant? limitations? posix compilance? implemented fully?
