inb4 some smartass says mmap is the second coming. I've been burned every which way using mmap. only use it when you identify a specific case that is sped up. a few examples that have worked are: linear indexes that involve a lot of seeks. fancy memory configurations like transparent ring buffers. loading executable code... trouble starts when you do multi process sync, interact with networked filesystems, windows, or green threaded runtimes
