g10k hangs when exiting on darwin/arm64

[mxey]

g10k is affected by gosuri/uilive#44, causing it to hang indefinitely on macOS on arm64 when it calls os.Exit.

$ timeout -v 3 go run . -version
g10k    Build time:  UTC
timeout: sending signal TERM to command ‘go’

interestingly this does not happen if an amd64 binary is executed via Rosetta:

$ GOARCH=amd64 timeout -v 3 go run . -version
g10k    Build time:  UTC

It can also be fixed by downgrading uilive to 0.0.3:

$ go get github.com/gosuri/uilive@v0.0.3
go: downgraded github.com/gosuri/uilive v0.0.4 => v0.0.3
$ go mod vendor
$ timeout -v 3 go run . -version
g10k    Build time:  UTC

Since uilive has not been updated in years, I would recommend replacing it entirely. I'm not sure what it's used for.

For reference, this is the stack trace of all goroutines I get when triggering a SIGQUIT:

$ go run . -version        
g10k    Build time:  UTC
^\SIGQUIT: quit
