 If random points is applied to a complex shape (I'm taking ITA_adm0, I
 think from OSM), generating even a few points takes ages, while CPU goes
 to 100%. With 1 point it takes a few seconds, with 10 it is already very
 slow, with 1k points I had to force quit. This on a low power machine, 4
 cores Intel(R) Atom(TM) CPU N550   @ 1.50GHz.
