It looks like it used to print out to STDOUT but it was changed in Bug 11679.

After reviewing the code, I'd say it was probably a desire to make the code
more readable/easier to maintain. However, it does create this performance
problem.

Fixing the "tab" and "csv" export should be fairly trivial, but the ODS will be
harder since it's a more complex file format (ZIP compressed XML). 

I'll write another comment about that...
