since this guy deletes the .Rlibrary, and it wants to leave things in a state where the h2o_master_test doesn't have to install packages (because it does parallel R)...install the list of packages used by 'all' the runit tests, after deleting .Rlibrary. Maybe have the rethink the pros/cons of restarting the personal libary (maybe we should install the runit-used packages in the site library using sudo?)
Merge branch 'master' of https://github.com/0xdata/h2o
