 // A controller for the Mac hung renderer dialog window.  Only one
 // instance of this controller can exist at any time, although a given
 // controller is destroyed when its window is closed.
 //
 // The dialog itself displays a list of frozen tabs, all of which
 // share a render process.  Since there can only be a single dialog
 // open at a time, if showForTabContents is called for a different
 // tab, the dialog is repurposed to show a warning for the new tab.
 //
 // The caller is required to call endForTabContents before deleting
 // any TabContents object.
