Did you know that Coverity actively REMOVED checks for concurrency bugs?

It turns out that when the programmer doesn't understand what the tool says, managers believe the programmer and throw out the tool. Coverity was finding itself in situations where they were finding real bugs, and being punished for it by losing the sale. So they removed the checks for those bugs.

I'll revisit my opinion of multithreaded code when things like that stop happening. In the meantime there are models of how to run code on multiple threads that work well enough with different primitives. See Erlang, Go, and Rust for three of them. Also, if you squint sideways, microservices. (Though most people set up microservices in a way that makes debugging problematic. Topic for another day.)
