We recently enabled Use Repository Sharing option in mercurial because we need all branches and there is no such option - we used fake working copy (to have changes in build) before and were manually getting data from repository, also it faster and saves space as we have a lot of jobs for the same repository.
As a result we have full build on slaves instead of incremental build.
