The sample here sets a breakpoint on pid_max, which is what the sample
in sample/ does.

And the code here is out-dated (and incomplete). We can fix it, but
whenver someone changes the APIs, he may forget to update the comments.
We know comments never catch up with code.

So I inclined to delete it, and add a link to sample/.
