From 27500d529f7fb87eef8812278fd1bbca67bcba72 Mon Sep 17 00:00:00 2001 From: Ian Gudger Date: Thu, 9 Jan 2020 22:00:42 -0800 Subject: New sync package. * Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations.
