The only case that this does not support vs ".threads" would be some
hybrid where we co-mingle threads from different processes (with the

of any usage that looks like this.

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.
