Maybe I have not understood it, but at first glance that approach seems prone to race conditions. What happens if the next chunk is ready while the “onchunk“ event for the last one has not been processed? Does the “chunk” property get overwritten and the previous chunk's data is lost? -- Nils Dagsson Moskopp // erlehmann <http://dieweltistgarnichtso.net>
