[Discuss-gnuradio] scheduler internals

I have a flowgraph that is saturating my CPU, causing underruns.
I would like to find out the block (i.e. thread) that is loading the
cpu most heavily, in order to see if there's anything I can do to make
it lighter (and avoid having to try it on a more powerful system).
I have run "top" and pressed "H" to show threads, and see a lot of
"python" threads, most of them under 10% cpu load, and only one of
them at 49% cpu load, so that one is likely the culprit.
Is there some way to extract this information from the GnuRadio scheduler?
