Interesting to see an ebpf approach to this idea, some time ago I did the same with Dtrace: <a href="https://gaultier.github.io/blog/detecting_goroutine_leaks_with_dtrace.html" rel="nofollow">https://gaultier.github.io/blog/detecting_goroutine_leaks_wi...</a><p>However I did not think of observing the ‘castgstatus’ runtime function.<p>Always nice to be able to compare the DTrace and Ebpf approaches, they both have different strong points.

that is actually sick.<p>how common is it for go devs to experience leaking goroutines ? id like to think go is a lot less shoot yourself in the foot here since they provide a framework for concurrency/parallelism rather than you working with the tiny pieces of it and building out the architecture yourself, but ive only needed to use goroutines once and it was a pretty problem-free experience.

Cool! is there something similar for async rust ?

So cool! Does it support multiple Go versions?
