Log which workpool is logging

Running into something like:

```

```

after we've removed a function, I'd like to be able to clear the workpool out. We have workpools that basically retry forever, and quite a few of them, and based on these logs I don't know which function we've removed, and what workpool it was scheduled in, so I can clean it up.
