[vbox-dev] high cpu usage after hibernate mode

Somtimes, I noted that vbox uses rather high cpu (50%) on windows host. The steps:
run vbox with an XP vm, check host cpu use, which is very low (5%), then hibernate the windows host. After Windows resumes from hibernate mode, the host cpu use is now much higher, about 50%.
Interestingly, the guest cpu is still very low (<5%).
This indicates that the vboxdrv.sys does not handle power well? Is there any IRP_MJ_POWER handler?
