+Blink overrides ArrayBuffer's allocator with its own one, while Node simply
+uses malloc and free, so we need to use v8's allocator in Node. As part of the
+10.6.0 upgrade, we needed to make SerializerDelegate accept an allocator
+argument in its constructor, and override ReallocateBufferMemory and
+FreeBufferMemory to use the allocator. We cannot simply allocate and then memcpy
+when we override ReallocateBufferMemory, so we therefore need to implement
+Realloc on the v8 side and correspondingly in gin.

+
+Only one X11ErrorTracker should exist at a time, but upstream has a bug
+where two can exist if running in headless mode --
+  ui::(anonymous namespace)::SupportsEWMH() [inner tracker is created]
+  ui::WmSupportsHint()
+  ui::IsX11WindowFullScreen()
+  ui::ScreensaverWindowFinder::IsScreensaverWindow()
+  ui::ScreensaverWindowFinder::ShouldStopIterating()
+  ui::EnumerateTopLevelWindows()
+  ui::ScreensaverWindowFinder::ScreensaverWindowExists() [outer tracker created]
+  ui::CheckIdleStateIsLocked()
+  ui::CalculateIdleState()
+Removal of either tracker could have side-effects in some code paths,
+so this is probably better handled upstream. This patch tries to do the
+least harm in the interim by removing the check that prevents more than
+one tracker from existing at a time.
