bq. Separate interface? Can we not push this feature down into all
RetryingCallables?
This makes sense for the replica callables.. So it's done for those only.

I suppose so. Proper interrupt handling in client RPC is something to address
separately.
bq. I don't think we need to add synchronized here. Can you see a reason for
this?
I was thinking another thread could access the instance, check it's
{{isCanceled}}, take some action even though the request hasn't actually be
canceled yet. Other than defensive coding, I don't have a specific problematic
interaction in mind.
lgtm, +1
> Improve cancellation for the scan RPCs
