My understanding is that MPS sometimes needs to stop Emacs, just like
the traditional GC does. And I was hoping to see how frequently such
stopping happens in practice compared to old GC. So, I fired the
profiler and saw the above output.

Now, the question is whether the profiler output wrt "Automatic GC" on
scratch/igc branch represent the moments when Emacs is being properly
frozen.
