The above statement means that you have some incorrect ideas how Linux virtual memory works. > If there's no need for the code, it won't be read back in again. That's how it works already, and was working this way for decades. Pages in file-backed mappings are loaded on access, not when mapping is created. Later, if a loaded unmodified page is dropped due to memory pressure, it will be reloaded only if/when accessed again. _______________________________________________ busybox mailing list [email protected] http://lists.busybox.net/mailman/listinfo/busybox
