[RFA] let record_resume fail immediately on error

To me, I see internal_errors as programing errors. From what you are
saying above, calling error would be more appropriate.

Taking a step back, if you had in fact hit a resource limit in
do_record_message, wouldn't it have been better to report the error
there? The error could then be a lot more precise and informative.
However, I see that do_record_message is a simple catch_errors wrapper,
so the error would be trapped, and your error-condition-checking code
would not trigger (catch_errors return zero in that case)... In any
case, these are just idle thoughts - improvements if any can be done
as part of another patch.
