write(2) 1022 bytes

read(2) 1024 bytes in process_read_output

successfully. The 1033 bytes read are the 1022 bytes written
successfully after processing (for example with CRs added if the
terminal is set up that way which it is here). The same bytes will
be seen again in a later read(2), without the CRs. */
