VBoxNetDHCP.exe wakes up CPU every 1ms, drains battery and makes noise

Description
When VBoxNetDHCP.exe is running on my Win 7 32bit system, my laptop makes a high pitch noise (~1KHz) and the battery drains a lot faster than when it is not running. My suspicion is that VBoxNetDHCP.exe is waking up CPU every 1ms, also when no VM is active. I do not see a reason to do that in a DHCP daemon. Hence I see this as a defect/opportunity for improvement.

Did you start VBoxNetDHCP manually? Because AFAIR normally it wouldn't start if no corresponding VM is running. If you started VBoxNetDHCP manually, how did you do it (which command line options)?
