I also looked at the code and don't see any mismatches (including those called from the `ACQUIRE_SURFACE` macro). I suppose you could restore the call, but since we are in a disposer thread throwing an exception doesn't seem like the right thing to do. You could log the error, but if we are sure there can be no pending errors, it might not be worth the effort.
