/*
 * Note:  Even though we create this plugin to deal with memory events from the system for handling OOM,
 * there is no code further down the line that actually handles them.  We totally ignore these events.
 * This is because the system has too high of an OOM threshold.
 * I.e. the system may only have 6m left and think it's out of memory, however, the browser can still render
 * many pages in only 6m.  So, these system events are ignored and the browser handles OOM with its own mechanism.
 * (See OOMStopper and OOMHandler)
