org.apache.derby.iapi.store.raw.Page.unlatch()
Unlatch me, the page is exclusivly latched by its current user until this method call is made.
After using this method the caller must throw away the reference to the Page object, e.g.
```
 ref.unlatch(); ref = null; 
```
The page will be released automatically at the close of the container if this method is not called explictly.
