Hello, Once you have written out your values to the map, you can read them concurrently and safely. If you need to write again to it (insert or delete), then you must ensure it is done safely.
Note that, from what I can see in tip, in 1.9 there will be a safe concurrent map: https://tip.golang.org/pkg/sync/#Map.
