Was this just something you found while debugging your code?

Don't really understand what is going on here either.

Argh, sorry missed this comment.
It's because we had the following construct in the new code:
if a:
b = set()
def foo():
if a:
b.add(1)
foo()Where if a is false, b is unbound and so cell.cell_contents raises a ValueError: cell is empty

I'm not sure if you purposefully used a new transaction description or not (it used to not have the _ in front of it I think).

Oh, doesn't really matter. Though unintended consequence of this means we're not going to confuse the two types of transactions in the graphs

Yeah sometimes I feel like it is desirable to re-use it, even if it isn't apples-to-apples. I guess that's more important with cache names, maybe. 🤷
