*	Optimise queueing of inbound replication commands (#7861)	Richard van der Hoff	2020-07-16	1	-0/+1
	When we get behind on replication, we tend to stack up background processes behind a linearizer. Bg processes are heavy (particularly with respect to prometheus metrics) and linearizers aren't terribly efficient once the queue gets long either. A better approach is to maintain a queue of requests to be processed, and nominate a single process to work its way through the queue. Fixes: #7444
