> show how to easily trigger races & deadlocks? I mean, the Go team needs to be aware of these problems and provide a fix or something.

You mean file a bug like "issue #1935 -- stop sharing memory between goroutines" (I just made it up to be silly there is no such bug report)

In other words, they have explicitly designed in the ability to share memory between goroutines. You can certainly file an issue or bug report about, somehow I doubt that will lead to much but being kickout and laughed at.

One can also just have 2 goroutines wait on each for results and that's a deadlock. Maybe there is a tool to detect that would be nice. Do you know of one?
