ENH: enable profiling output for postProcess and -postProcess (closes #526)

- added an explicit print, but only report profiling to the log
  file from master process.

  We don't wish to overwrite any profiling that was conducted during
  the simulation. Besides which, we don't have a proper Time object
  for handling the write nicely either.
