你遇到过的源代码中最好的注释是什么?

来自Linux内核源代码:

linux /包括/ asm-i386 / hw_irq。h:

/*
 * subtle. orig_eax is used by the signal code to distinct between
 * system calls and interrupted 'random user-space'. Thus we have
 * to put a negative value into orig_eax here. (the problem is that
 * both system calls and IRQs want to have small integer numbers in
 * orig_eax, and the syscall code has won the optimization conflict ;)
 *
 * Subtle as a pigs ear.  VY
