(削除) sys.dump_executors() (削除ここまで) sys._dump_tracelets() dumps out a diagram of the current executors in graphviz format.
It is a bit hard to understand what's going on as it doesn't show cold exits, how well executed the latter parts of traces are, or where it exits to tier1.

With a bit of highlighting and colour, the diagram could be much easier to understand.

I propose adding:

• Edges for jump-to-top
• Markers to show exits that haven't warmed up
• Shading to show parts of traces that are relatively cold
• Warning markers for _DEOPT and other poorly performing uops.
