I would like to propose another topic: * Enhancing on-demand paging algorithm on NuttX: - It already has a rudimentary on-demand paging algorithm that allows mapping the `data` memory on-demand ( https://nuttx.apache.org/docs/latest/components/paging.html#kernel-build-implementation). However, it doesn't allow loading applications from the read-only device on-demand (it copies `text` area at once) and neither it contain an algorithm to handle when physical memory allocation fails (like identifying unused memory and writing to a flash partition, like the Linux's "swap partition").
