Because that patch was partly extracted out of a bigger one, and I was both lazy and worried about breaking things close to the release. In other words more uses of the mutex are coming, and it will need to be shared between jobs to work fine with transactions and monitor commands (which don't know the job they're working on until they've looked it up). Starting a paused block job is not a hot path. :) Paolo
