If you're doing any other I/O, you may be surprised by where the trace output shows up relative to it.
How about if the "I/O" is to write to a different stream? Then it wouldn't matter too much. Or perhaps updating a real progress bar widget on a GUI. Or - better still - frobnicate an MVar or something. (Then you can handle what you do with these "update" signals somewhere else without cluttering the main algorithm too much...)
