Hello.
I noticed that window7, unlike windowsXP as I played with
previously, poses quite high load on host when idle. On
my machine, host cpu usage is about 25% when one single-cpu
win7 guest is running with "-usbdevice tablet" option.
Here's a typical kvm_stats when such a guest is idling:

During this shot, host CPU was about 30..35% in use - higher
than usual 25%, but I guess it's due to perfmon.
Please build qemu with --disable-strip and use 'perf' to profile it.
Done, I tried several differ

Maybe we'll see a lot of context switches in there.
