Google Chrome results in a "Sad Tab" screen of death, similar to the well-known "Sad Mac", but only one tab crashes instead of the whole application. This strategy exacts a fixed per-process cost up front, but results in less memory bloat over time as fragmentation is confined to each instance and no longer needs further memory allocations. This architecture was adopted in Safari and Firefox. Chrome includes a process management utility called "Task Manager" which lets users see what sites and plugins are using the most memory, downloading the most bytes and overusing the CPU and provides the ability to terminate them.
