From 45fcd758a07fef44a8773202b13f469c9636dffc Mon Sep 17 00:00:00 2001 From: Heikki Linnakangas Date: Thu, 19 Jul 2018 16:08:09 +0300 Subject: [PATCH] Rephrase a few comments for clarity. I was confused by what "intended to be parallel serially" meant, until Robert Haas and David G. Johnston explained it. Rephrase the comment to make it more clear, using David's suggested wording.
