This fixes a bug where QEMU stall in icount mode.
It happens when a simple timer callback is created on VIRTUAL CLOCK modding
itself regularly.
The actual warping mechanism is called once and then the time didn't grow
anymore.

Paolo,
You mentioned some icount patches (I can't find where) can you point me
to them?
Did you already had this bug?
Thanks,
Fred
