Maybe some idle timer? IIUC, after adding compilation--ensure-parse there is no performance degradation in case when the compilation buffer is displayed during compilation, because compilation--ensure-parse is called on the same-sized chunks as when the buffer is fontified by font-lock. I noticed this when tried to debug the problem of fontifying diff hunks, but I failed to find a solution. The problem is this: sometimes diff-mode doesn't refine some hunks during font-lock when the first part of the hunk emitted by diff-process-filter (from the diff command comparing files) is fontified partly, then after emitting the remaining part of the hunk it remains unfontified.
