This is a really great tool - the kind I didn't even know that I needed until I was given it!

One question, does anyone here know how to interpret the GIL (Global Interpreter Lock) percentage display in the top-left? In my code, "Active" sticks nicely at 100%, but the GIL jumps around from 1% to 100%, changing on every sample.

edit: Now that I think about it, my code spends a lot of time in C API calls - maybe the GIL is released there?

Wow, it tracks GIL contention? Major feature for me. I use a lot of Numba, and it releases the GIL if you want — so threading is actually useful.
