I use it a lot.

Mostly.

Maybe sometimes.

The long answer:

Lua coroutines are _really_ nice. They are very fast, very usefull and
very light weight. I use coroutines in all sort of iterators.

However, sometimes they are a little bit limited, because they can't
yield across a C-boundary. But in the meantime I changed my software
layout to work around this limit. I played with C-level coroutines. But
they are simply to expensive.

So the lua way is to go with lua coroutines.
