Use some form of non-blocking IO

I think the best candidate for this would be LuaSocket as it:

• already has typedefs and
• is cross platform
• language servers have the option to communicate over sockets, but just use stdio by default
• And is one of the most popular lua modules so people probably already have it installed

but I'm open to other suggestions like luv or cqueues
