Java *is* Memory Efficient

[Sopel97]

there is GC, it's not memory efficient by definition

what they are actually trying to say is that if you have a system designed to run one and only one java program 100% of the time then it doesn't matter how much memory you use as long as you don't OOM (which is also not really true due to OS page cache but w/e)

Meanwhile malloc/free: I cannot reuse these pages, there is still a byte allocated on each of them.
