Hm, idk about adding another way to free memory. Why isn't using
ContextSupport::SetAggressivelyFreeResources enough?

+  if (bind_succeeded_)
+    gles2_impl_->FreeUnusedSharedMemory();
+}

 bool ContextProviderCommandBuffer::BindToCurrentThread() {
   // This is called on the thread the context will be used.
   DCHECK(context_thread_checker_.CalledOnValidThread());
