The tough part is not to get these things to work, or even to make them
efficient. The problem is to come up with a simple, consistent and
portable interface that will make most people happy.

The next version of LuaSocket will probably support IOCP on Windows.  If
it does, it will be in association with a built-in coroutine dispatcher,
similar to the one in Copas. I will avoid using threading as much as
possible.

It is unlikely that I will rewrite Lua's standard IO library to work
with the same dispatcher. But I promise to think about it.  I will be
bothering Mike Pall and David Burgess a lot with this subject in a
couple months.

Diego.
