. Without protection such as afforded by WSRM, the app runs more slowly and eventually crashes, because the misbehaving app eventually causes problems that affect every app that shares its
memory space. With WSRM, an app can be limited to an isolated subset of hardware resources. As a result of this, the bad effects caused by the memory leak is limited to that subset.
