mod_pep: Remove use of RLU cache when persist_items was set to false This behavior came from some confusion over the meaning of persist_items. The correct behavior is that items are only stored when it is set to true. When set to false, the service becomes a "pure" publish-subscribe service, where items are forgotten immediately after broadcasting.

local xpcall = xpcall;

if select(2, xpcall(function (x) return x end, function () end,  "test")) ~= "test" then
	xpcall = require"util.compat".xpcall;
end

return {
	xpcall = xpcall;
};
