[Qemu-devel] [PATCH] Moving alarm_timer assignment before atexit()

[Amos Kong <akong@redhat.com>]

We register exit clean function by atexit(),
but alarm_timer is NULL here. If exit is caused
between atexit() and alarm_timer assignment,
real timer can't be cleaned. So move alarm_timer
assignment before atexit().
