Quick tvheadend suspend question

If xbmc-pvr is set to auto suspend after inactivity will stay awake if tvheadend is recording?

I think not.
I have windows mediacenter running its recording services, as I still use this for recorded tv.
And XBMC suspends the whole PC if it is set to suspend.
So it does not monitor any activity outside it´s own shell i presume.
Also if another xbmc pc is playing a movie, where the file resides on main pc it also shuts down.
Again not monitoring network flow and hdd access outside the xbmc shell.
What I have done is set xmbc to close after a period of insactivity, and the rely on windows 7 powermanagement for the suspend of the system.
And this works.
XBMC close after 15 min.
Windows 7 suspend after 30 min, of idle
This respects recordings and other pc pulling data from the drives

I should have said this is xbmcbuntu.

I would have hoped the pvr version would see that there is a recording active as activity. If this is not the case then will setting the suspend option within ubuntu itself detect tvheadend recording?
