(Broken since 2006). 3) you really can get the same information from "top" now that we have VCPU threads. 4) It declares non-existing extern variables qemu_time_start and tlb_flush_time, the latter of which has never existed _at all_. But let's fix it.
Sure! Who/how? :) Or fixing means removing it? I am not using it, it is in my configure invoke script for ages.
