Only accepts a single tab ID as a parameter, not an array.

The tab ID argument is optional: if it is omitted, the browser discards the least important tab.

The callback is passed a Tab object representing the tab that was discarded.

Tabs whose document contains a beforeunload listener that displays a prompt will be discarded.
