我刚刚注意到自己在写这个

// not brilliant solution, but fair enough heh.

在linux 1.0内核调度器(schedule .c)中:

Dijkstra可能讨厌我。

/*
 *  'schedule()' is the scheduler function. It's a very simple and nice
 * scheduler: it's not perfect, but certainly works for most things.
 * The one thing you might take a look at is the signal-handler code here.
 *
 *   NOTE!!  Task 0 is the 'idle' task, which gets called when no other
 * tasks can run. It can not be killed, and it cannot sleep. The 'state'
 * information in task[0] is never used.
 *
 * The "confuse_gcc" goto is used only to get better assembly code..
 * Dijkstra probably hates me.
 */
asmlinkage void schedule(void)

摘自UNIX版本6源代码，大约1975年:

/* You are not expected to understand this. */

//todo: never to be implemented

//FIXME: fix this before the 1.0 release
