changed the title
This saves a system call by sending the frame header and the chunk header at the same time. References rabbitmq/osiris#192
Osiris can read ahead data in case of small chunks. This saves system calls and increases consumption rate dramatically for some streams. This is transparent for the stream protocol, but requires a small tweak for the stream queue type implementation (passing in the previous iterator when creating a new one). The read ahead is on by default but can be deactivated with to the new stream.read_ahead configuration entry (true / false).
