by Andreas EversbergAdd multiple messages buffers to io_uring write operations
Multiple message buffers can be writen by sending a single SQE when
using io_uring. If there is less data written, the completely written
buffers are removed and the partly written buffers are truncated.
Afterwards they are re-queued for next write operation.
Having more than one buffer is optional and the number can be controlled
via environment variable.
