There is no doubt that, to break detach() is absolutely a bug. When it is true that it was a workaround to use detach() in my original code, please remember that it is absolutely valid to detach a thread. I can choose to keep the detach(), and there is nothing wrong with that.

Now to those people who wish to detach() their threads, they have to implement a workaround without detach(), and then put detach() back when it is fixed. Is this a "overall win" to us?

"I don't see how you can talk about poor QA when the p5p folks explicitly mention that they're aware that the new code is problematic."

If they explicitly mentioned that they knew detach() is broken, I would probably say nothing about their QA, but that is simply not the case. After all, it is not me talking about the poor QA, but detach().

"...this fix-date release..."

What makes the "fixed date" more important than the quality of the release?
