I do this exact same horrible horrible thing too, but in these
conditions it should often be better to use "--redirect-stdout"
as an alternative, which spits each processor's messages to its own
file.  Time stamp everything or stick in a few barrier() calls so you
can infer message ordering, and that way you don't end up waiting
forever when you're trying to debug something deep in a loop.
