A large gettext file. I created on from Gutenberg's Moby Dick.
Many languages for the project are enabled, e.g. the default language set as seen on t.z.o
1. Upload a large gettext file to a project version. Go back to the projects page
2. Clone the version by clicking the down arrow on the version and selecting Copy to new version
3. Enter a new id, and press create
4. Repeat steps 2 - 3 on the same original version
Two versions are now being created. Where one version would take some minutes to complete, this one takes around an hour to fail (out of heap space). At least, it did on my machine (T530, 8GB RAM, i7-3520M CPU @ 2.90GHz)
