If you are fixing READ2 to allow a vector based reply, please also
consider allowing an error to be part of that vector. The protocol
currently has an issue where it is non-obvious how to return
an error encountered midway through a long read where some
data has already been sent to the client (from memory
i.e. unless it's already been fixed).
