definitely no chance that sink==nullptr?

This is never used?

No.
If this was pure WebCore code, the addObserver/removeObserver would take references and m_sinks would be a Vector of std::reference_wrapper.
We could still do the latter but the removeObserver would contain more lines of code.
Maybe we should specialise Vector when containing sd::reference_wrapper though.

I initially thought of having just one m_blackFrame but the buffer pool is probably good enough for now. Removed this declaration.
