I don't see why...OS X had a default limit of 100 processes per uid (increased to 266 in 10.5) and "it works" (many people notices it, but it's not surprising since the limit is too restrictive). If you don't have limits, you can't avoid starvation easily. From my experience, since I use CFS, fork/compile bombs (forgetting to put a number after make -j...) are very sluggish mainly because the whole graphic subsystem is paged out. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
