cleanup: append pointer instead of value to avoid copying lock value

Browse Source 
This commit resolves the govet issue -
`copylocks: call of append copies lock value ... contains sync.Mutex`

Embedding DoNotCopy in a struct is a convention to signal and prevent
shallow copies, as recommended in Go's best practices. This does not
rely on a language feature but is instead a special case within the vet
checker.

For more details, see https://golang.org/issues/8005
