A sufficiently well resourced Linux will run quite happily sans swap. There is even a kernel option to turn off the swap daemon. Happens all the time in the embedded market. In a normal environment, I don't think I'd want my largest memory consumer(s) subject to the out of memory killer (yes, such a beast exists). They tend to be the folks you actually want to protect (think any database you've ever seen), but oom_killer makes its own decisions - generally biggest and/or fastest acquirer. I haven't looked at z/Linux to see if that ported, but I'd be surprised if not. > Is the "sticky bit" in unix akin to LPA to allow the same code to be > shared between users? I hope it's reentrant.... Shared libraries are widely used, but tend not to be "resident".
