This is because in the past we would register the go channel handler in a deterministic location (ie, bzltestutil), but now since its injected into main(), the name depends on the name of the target, which is not deterministic to ignore.

We should bring back the RegisterTimeoutHandler so we have a deterministic location to ignore again.
