[Qemu-devel] [PULL 39/79] replay: flush events when exiting

[Paolo Bonzini]

From: Pavel Dovgalyuk <address@hidden>

This patch adds events processing when emulation finishes instead
of just cleaning the queue. Now the bdrv coroutines will be in consistent
state when emulator closes. It allows correct polling of the block layer
at exit.
