doc: add note about missing lock in sample code

The sample code in 'Interfaces and methods' section contains a
data race. Handlers are served concurrently. The handler does write
and read operations; `go test -race` would fail (with concurrent
requests). Since the doc is frozen and the code remains less
cluttered without locks/atomic, don't change the sample code.
