Currently, even if you define your own AbstractLogger and set Base.global_logger(mylogger), worker loggers still prepend " From worker X: to all logs.

My current work-around is doing

using Distributed
function Distributed.redirect_worker_output(ident, stream)
           @schedule while !eof(stream)
               println(readline(stream))
           end
       end
using MyPkg
MyPkg.run()

So hurray for JuliaLang/julia#265 and all, but we really need better controls here.
