There is no need at all to be sorry. This is exactly why I placed this as an RFC. While your points simply enforces why I feel a solid illustration of threads is needed. Moreover, I agree that this example may not be it, but at least the topic is raised.

Next, many will say just use module X or module Y to solve this or that thread problem. However, did one really learn how to do it, or did they just learn a shortcut that they may not have in the future? Me, I prefer to learn and understand.

Finally, I have great respect for your comments and thoughts, as I see you have actually authored several write-ups. While others tend never to pass knowledge on and consistently stand in judgement of those that would. So, no apologies are needed. --Poet
