There are no significant advantages beyond improving the code, but
I do this in preparation for the next commit.

In my tests with 37128 faces and a batch size of 5000 it improves
memory consumption by 38,81%.

I guess we can celebrate a little. 🎉 😉

In my tests this improves memory consumption by another 3.14%. In
total against version 0.9.51 we achieved an improvement of 41.89%.

1.10 % less memory, totaling 42,99 % reduction..
