I understand you are worried about newbies misuse APIs. You remind me that I should add a warning to inform the sample code in this article should not use in programs. Thanks.

Also, I did not advocate a newbie should start and stop threads by themselves. I want to say I agree that we should use high-level APIs in most cases, but, in some cases, we may need to use low-level APIs to achieve our missions. I am unwilling to limit what kind of APIs should use. In my opinion, like you said: "you have just seriously over-architected the solution," we should be careful to use APIs. Even though high-level APIs are safer, programmers may misuse them.
