Memory leak in Node 8.9.3

[WingUNO]

I'm using Node: 8.9.3, cls-hooked: ^4.2.2.

There's the memory snapshoot:

I found this:

async hooks promise not destroyed

Certainly，I update Node to version 8.15.0。No memory leak any more.

So, cls-hooked dependency, Node version should update to the right version instead of 8.2.1

Oh I found that this memory leak is not caused by cls-hooked。I found the real reason:
nodejs/node#23410
