Is there something in place to support parallel IO? I’m currently thinking in the context of MPI, where it is nice to have functionality such as only printing on the first rank or prefixing lines with the process rank. Or more challenging, make sure output from different ranks is neatly separated on…

DevNull is not quite /dev/null but the folowwing should work redirect_stderr(open("/dev/null", "w"))
