I guess I live in a different world. I do lots of things I'm not "supposed" to do.
Moreover, it is very sensible and usable to mprotect malloc pages. I have implemented simple sandboxing this way. For my dissertation I implemented a DSM by mprotect'g malloc'd memory. This system worked for >6 on several version of Linux and SunOS. I actually have a better track record for this technique than for some things that are within the specifications.
