Thrown Error not raised unless data gets printed to stdout beforehand

# NOTE:
# uncommenting either of the two `console.log ''` lines bellow will "fix" the problem, and the error message will be printed to stdout.
# Also interesting: if the line `console.log 'in finally'` is replaced with `util.debug 'in finally'`, the problem comes back (i.e. even with the log lines uncommented)
