net.server_epoll: Optimize concatenation of exactly 2 buffer chunks Saves a function call. I forget if I measured this kind of thing but IIRC infix concatenation is faster than a function call up to some number of items, but let's stop at 2 here.

local type s2s = function (s : string) : string
local record lib
	to : s2s
	from : s2s
end
return lib
