Your recommendation to get at least 256 MB is perfectly sensible, but the fact 
remains that some people still _do_ use machines with less memory than that. 
With small memory, they may well be aware of the potential for OOM 
situations and take precautions against it. They wouldn't necessarily welcome 
memory locking if that made normal performance (which isn't likely to be great 
anyway) worse.
