This patch adds a Priority and a Machine menu to the menu bar.

The Priority menu controls how much cpu time qemu receives, and the  
Machine menu has the Restart menu item for restarting the emulator.

Please do not combine unrelated changes into one large patch.

I'm not sure if adding more menus to QEMU is the way to go,  
considering that this has traditionally been the job of frontends like  
Q. I haven't noticed such options in the SDL frontend either.
What I am missing though is the system-provided Services menu item in  
the application menu.

What exactly are you trying to accomplish with this patch?

This is most certainly the wrong way, you are blocking the event loop  
during a pending update for one second.
If you want to throttle events like screen updates or reduce the QEMU- 
induced CPU load, this likely needs to be done in another way, putting  
less events into the queue in the first place, no?
