Yes, and i think this would be a first version(s) of Cog VMs, which
could be titled as 'stable'.
Because the bug, which Eliot fixed are really vicious and were plagued
us for more than half of year.

(i preparing an update on jenkins build server, we will see how well
it goes after the fix).
Because now we having a test jobs on jenkins which running tests for
newly built VMs (but i will write more details in separate post).
