I really need some users by now, for those two reasons:

* I'm at a point where I fully covered my own needs (the reasons I started coding this), and getting some users is the only way to learn about what other people might need
* The complexity "exploded" after supporting so many OS-specific APIs (like #kqueue, #epoll, #eventfd, #signalfd, #timerfd, #eventports) and several #lockfree implementations based on #atomics while still providing fallbacks for everything that *should* work on any #POSIX systems ... I'm definitely unable at this point to think of every possible edge case and test it. If there are #bugs left (which is somewhat likely), I really need people reporting these to me

Thanks! 🙃

I now experimented with different ideas how to implement the #lockfree #queue for multiple producers and multiple consumers. Unsurprisingly, some ideas just didn't work. One deadlocked (okaaay ... so it wasn't lockfree) and I eventually gave up trying to understand why.

The "winner" so far is only "almost lockfree", but at least slightly improves performance. Throughput is the same as with the simple locked variant, but average response times are 10 to 20% quicker (although they deviate stronger for whatever reason). Well, that's committed for now:
