[vbox-dev] (no subject)

Hi,

when waiting for a blocking program in the guest called by

"VBoxManage guestcontrol execute --wait-for exit ..." 

there is a significant increase in CPU load on the host. 
This is caused by both processes VBoxSVC as well as VirtualBox, although the program in the guest does not cause any load within the guest.
This behavior was observed, on Windows 7 and Linux hosts, with VirtualBox Versions 3.1.10, 3.1.12 as well as the new beta 4.0.

Is this working as designed or is there some inefficiency in the polling mechanism?

   Regards,

   Norbert
