Source/WebCore/platform/MemoryPressureHandler.h is for releasing memory when there is memory pressure.  It looks like it's only implemented on OS X and iOS.  Maybe we should implement this for Chromium too?

It looks like we already have some hooks in WebCore/platform/MemoryUsageSupport.h for when we gc in V8, but looks like we can do more here (see all the stuff that gets cleared in MemoryPressureHandler::releaseMemory in the .mm file).
