Review Comment:
This is a small change for such a large conversation but looking at the
stdlib, I don't see any checks like this.
* close a nil `http.Server`: panic
* close a nil `io.ReadCloser` from an `http.Response`: panic
* close a nil `sql.Conn`: panic
In general you should not be calling methods on nil pointers. I don't think
we want to start some sort of precedent that we're going to be safe guarding
callers who aren't checking for nil. This codebase is filled with pointers and
methods that aren't guarding against this and I don't see the value in fixing
one spot let alone spending the time to fix all of them.
