If I understand you right; this is a fairly common thing with RT where we would stuff all the !rt threads of the various processes in a 'misc' bucket. Similarly, it happens that we stuff the various rt threads of processes in a specific (shared) 'rt' bucket. So I would certainly not like to exclude that setup.
