When the applet API was reviewed to use dedicated buffers, the support for sends from the streams to applets was added. Unfortunately, it was not a good idea because this way it is possible to deliver data to an applet and release it just after, truncated data. Indeed, the release stage for applets is related to the stream release itself. However, unlike the multiplexers, the applets cannot survive to a stream for now. So, for now, the sync sends from the streams is removed for applets, waiting for a better way to handle the applets release stage. Note that this only concerns applets using their own buffers. And of now, the bug is harmless because all refactored applets are on server side and consume data first. But this will be an issue with the HTTP client. This patch should be backported as far as 3.0 after a period of observation.
