Some changes made last month led to increased CPU usage by host even when guest OS is idle.

This is found for x86_64 host with qemu-system-x86_64.
Qemu process uses about 20-50% of one CPU, as seen by htop.
Result doesn't depend on guest OS: Knoppix and Win2k3 tested,
It doesn't depend on details of host CPU - 2 different computers tested - but they are both dual-core amd64-compatible intels.
Result doesn't depend on network, nor display configuration of guest.
