Larger world crashes minecraft on low-spec windows boxes

Importing a larger world (158 mb populated village with some mobs in current chunk) crashes on Win 10 tablet (2GB RAM, 32 bit OS)

 

The world once started out on the device and had problems already then and only loaded the save file 1 out of 4  times when in a populated village.

 

Expected behaviour:  Graceful abort with an error message if world is too large when importing / loading / exporting. Option to give feedback to Mojang that the problem is out there.
