Hi,

There is a quite annoying thing, don`t sure if I can call it a bug.

How to reproduce:

- start a bunch of VMs,
- stop libvirt,
- start libvirt and immediately issue any call, say, 'virsh version',
- delay until call completion may be fitted nearly as quadratic
function from number of running VMs, qemu-kvm in my case (see link
below). After this delay passed, any calls executed without slowdown,
so problem is only a 'dead gap' after restarting service.
