Stop me if I misunderstood the case at hand, but while waiting some more
for having a sizeable batch to send makes a lot of sense to me, waiting
on the receiver side when there's some work to do will only forbids a
slow slave to keep up with the load, increasing lag artificially.

I'm used to asynchronous replication where you're never allowed to rest
if some batch is ready for you to process.
