From 377b21ccea1755a8b0dae822c29567c58dda6939 Mon Sep 17 00:00:00 2001 From: Pavel Dovgalyuk Date: Tue, 27 Feb 2018 12:52:14 +0300 Subject: replay: fix save/load vm for non-empty queue This patch does not allows saving/loading vmstate when replay events queue is not empty. There is no reliable way to save events queue, because it describes internal coroutine state. Therefore saving and loading operations should be deferred to another record/replay step.
