maybe more straightforward to just make idleConns an atomic int as well and inc/dec when freeconn changes?
code.google.com is in archive/maintenance mode, and redirects the original URL to: https://cloud.google.com/appengine/docs/standard/go/memcache/reference Let's just use a godoc URL instead.
Replace code.google.com URL with godoc.org URL
* Use ReadFull instead of ioutil.ReadAll to read objects ioutil.ReadAll uses a bytes.Buffer, which allocates memory by doubling. Since we know exactly how muh data we expect to get, we can allocate it in advance. This reduces the total amount of allocation, and ensures that the slice stored in the item won't have excess capacity (which can affect memory usage if the item is held for a long time, for instance in a secondary cache).
This is mentioned in the Expiration field of the Item struct (no expiration time), but not in the notes about the Touch function.
- [go modules](https://github.com/golang/go/wiki/Modules) will be enabled in 1.13. - after merge it would be nice if you would tag this repo: e.g. `v1.0.0` - this will allow consumers something more consistent and readable than `v0.0.0-20181229203832-0af3f3b09a0a`.
* Add Ping method.
