We have been trying to benchmark with the load balancer patches and have
experienced some hard lockups with the saturated test cases, but we
don't have traces for now.

Since we are mostly focused on testing the rebased v4 currently, we will
post it without those patches and then we can try to debug more.

Thanks,

Julien
