Running virsh with the remote driver (as it always is on Solaris), it
leaks pretty heavily:
thewhip:~ # yes "start fewfewf" | virsh >/dev/null 2>&1 &
[1] 6388
# prstat -c -p 6388
PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
6388 root 10M 6788K sleep 59 0 0:00:02 0.2% virsh/1
Total: 1 processes, 1 lwps, load averages: 0.32, 0.12, 0.06

Can you reproduce on Linux anyone?

Yeah, it seems there is no limit on the size of the readline history,
so it just grows forever. Try this?

Thanks, I'd applied this patch.
If anyone is feeling motivated, it could be nice to have virsh load/save
its history to $HOME/.libvirt/virsh.history between invocations.
