Review comment:
> is there a uni test that can be added for this?
If there isn't already a failing test then one would need to be added for
using an `ipc.FileWriter` with `ipc.WithCompressConcurrency` set to a value
greater than 0. It should be trivial to add if tests for the `FileWriter` exist
already and I will add one tonight if this is the case.
