Scripts and programs are edited all the time, either by its original author or for modifications when downloaded. Maybe the original author forgot something when editing and suddenly its no longer safe. Or $tempdir isn't a unique name, meaning at different places (be it copy paste) could manipulate the global variable. Human errors happen all the time. Better do check in place, instead hoping that this stays safe. Alternatively create a tempdir with a fixed part in name, like "${tempdir}_protonge".
