This series finally fixes -icount with iothread and avoids deadlocks
due to the vm_clock not making progress when the VM is stopped.
The crux of the fix is in patch 1, while patch 2 implements the
"clock warping" that fixes deadlocks in v2. Clock warping uses
the nanosecond resolution rt_clock timers introduced by my previous
series.
With this in place, patch 3 can revert the previous attempt(s).
Finally, patch 4 makes the icount code clearer by finishing the
bugfix/reorganization of qemu_next_deadline vs. qemu_next_alarm_deadline.
v1->v2:
reordered patches, renamed qemu_next_deadline
v2->v3:
introduced warp timer
Paolo Bonzini (4):
really fix -icount in the iothread case
enable vm_clock to "warp" in the iothread+icount case
Revert wrong fixes for -icount in the iothread case
qemu_next_deadline should not consider host-time timers

On first glance, I've spotted a view coding style issues. Try checkpatch
(maybe excluding patch 3).
Will repost, testing is welcome in the meanwhile!
