Automatically Close Tabs in mobile Safari

Mobile Safari has a feature that automatically closes tabs. It reveals the ill-conceived nature of the interface as a whole:

The problem: tabs pile up indefinitely. This is because there is no reason to close a tab after you got from it all you wanted. However, when you create a new tab, the old ones vanish from view entirely, and don’t get in the way. It’s just that once every two months you’re horrified by the list of open tabs.
