The question is: What is the upside of having such a large limit?
The downside is apparent - it's not the memory usage but the time wasted =
when running secure software since you can't use closefrom because it's =
not portable and so libraries/ports/etc don't use it (or more =
realistically Linux doesn't have it).
Other limits like max processes scaling with memory makes sense but =
maxfiles should probably scale more slowly (or maybe even not at all..)
