Comment (by DarioOliveri <oliveridario89@…>):

 not only, calling "clear" does not reset memory! The only way actually to
 effectively make sure unordered map free all used memory is to make sure
 it goes out of scope (or wrap it with a smart pointer to be able to delete
 it).

 calling "clear();" followed by "rehash(0)"; seems to reduce memory usage
 to few bytes (but still some memory is allocated!)
