I wonder whether doing something in the runtime is possible. For 
example, it may be more resilient and not crash when suspending a thread 
fails because the thread may be dead already.

However, studying the runtime code around thread_detachThis three years 
ago, I had realized that like many things in computing, the whole 
stop-the-world is wishful thinking because there is no guarantee that 
your "please suspend this thread" request to the OS has succeeded. You 
get a success return code back but it means your request succeeded not 
that the thread was or will be suspended. (I may be misremembering this 
point but I know that the runtime requests things where OS does not give 
full guarantee for.)

(Going off-topic, even clicking on a user interface is wishful thinking 
because a few times a year I attempt to click on something but another 
window element pops under my mouse pointer and I unintentionally click 
something else, commonly on web pages as they are being rendered by a 
browser: links move around on the page. This used to bother me but not 
anymore. Life is not perfect and I appreciate it. :) )

Cool! :) It makes me a little sad that my online version is ahead of the 
paper version by a couple of years now. I want to update the paper as 
well but I want to work on work stuff like the topic of this discussion. 
:) (Related note: the ebook versions on the web page are more up-to-date 
than ones that you can buy especially because the versions on my web 
site include a table of contents section. Consider updating your ebook

I still think D is a great tool but some use cases can be tough and 
sometimes embarrassing. :/
