Great work. I found one problem on circleci.com. The for dir loop is creating odd dependency paths. ie.

scripts/goclean.sh
ok      _/home/ubuntu/wellington    1.024s
ok      _/home/ubuntu/wellington/context    1.030s
ok      _/home/ubuntu/wellington/context/handlers   6.189s
ok      _/home/ubuntu/wellington/lexer  1.012s
cover: can't find "context.go": cannot find package "_/home/ubuntu/wellington/context/" 

go test|vet|tool ./... is working fine, only the find command is causing this issue. I haven't quite figured it out yet, but you can check out the build in action here: https://circleci.com/gh/wellington/wellington/27

I wonder if the pwd is changing, and profile.cov needs to explicitly define a directory to dump in?

I'm using a modified version of this and noticed that when there is a race, it doesn't return an error from the test command unless you set an environment variable.

I'd suggest:
env GORACE="halt_on_error=1" go test -v -race ./...

Thanks.

I have just noticed that there are no notifications about the comments on Gist, I have just moved the script to my Git repository: https://github.com/hailiang/gosweep (name changed from goclean to gosweep to avoid confusion with "go clean" command).
