What't the thought about libuv event loop design

[monkindey]

I am interesting in the thought about libuv event loop design.Why the stages and order of the loop iteration is timers、pending callbacks、Poll、check、close ? Any thought and example on it ?

Thanks

Mostly because that's, by and large, what libev did.

Node.js used libev before it was ported to Windows. Libuv was written as a portable replacement for libev.
