No stderr output is displayed in the shell sometimes. It is probably an upstream bug in mafredri/zsh-async. Stderr is redirected by exec 2>/dev/null in function _async_worker within async.zsh.
Seems a known and fixed bug in zsh-async#35. But in my former experience, remove exec 2>/dev/null may not be enough, the stderr is still lost sometime after computer wakeup. Let's update zsh-async and wait for later test.
Still no idea why remove exec 2>/dev/null within zsh-async is not enough. After such a long time, I found a way to trigger this bug 100% at last.
Run go test on https://github.com/quii/learn-go-with-tests/tree/master/select/v3, and switch to another dir. fd 2 will be redirected to /dev/stderr every time I try this.
I'll just redirect fd 2 back after calling async_stop_worker.
