I indeed think we should consider the code in free_realized_fontsets a
possible culprit only if the profile shows it uses some significant
portion of CPU time in this case (or some other real-life case).
Based on where that function is called from, I don't immediately
understand why would it be a hot spot when looking for fonts.
