From https://youtu.be/YNSAZIW3EM0?t=1474: "Hmm... I don't think that name is right! From the perspective of userspace, this is a file descriptor. File description is what the kernel internally keeps track of, but as far as userspace is concerned, he just has a file descriptor. [...] Maybe that name should be changed." Core::File even has a member of this enum type... called m_should_close_file_descriptor - so let's just rename it :^)
