Title: multi.jl: worker finalization, remove :cmd, flush worker() info

Flushing here rids us of problems caused by buffering (recent STDOUT IOStream changes?). Additionally, we don't need :cmd anymore with the latest ClusterManagers.jl, and finalization lets us properly clean up after firing up a PBS/Torque or SGE instance (remove temporary working files, processes).
