FWIW, I agree with Robert on this. It seems just weird to call out
temp_file_limit specifically. Also, I don't agree that that's the
only interesting per-process resource consumption; max_files_per_process
seems much more likely to cause trouble in practice.
Perhaps we could change the wording of temp_file_limit's description
from "space that a session can use" to "space that a process can use"
to help clarify this?
