Unfortunately at this point there is no support of locking between

It will be quite tricky for implementation, because we have different load
generators, and we will need to find
common solutions for all of them.

If you have any ideas about how to implement it in such way, I will be more
than happy to get this in upstream.

One of the way that I see is to having some kind of chain-of-benchmarks:

1) Like first benchmark is running N VMs
2) Second benchmarking is doing something with all those benchmarks
3) Third benchmark is deleting all these VMs

(where chain elements are atomic actions)

Probably this will be better long term solution.
Only thing that we should understand is how to store those results and how
to display them.

If you would like to help with this let's start discussing it, in some kind
of google docs.
