--- Comment #4 from Chris chris.kcat@gmail.com 2008-06-03 14:01:30 --- The original issue seems to be patched (it doesn't keep the extra data buffered anymore), but it seems there's another related issue (not buffering on very small data lengths, such that 0 source bytes are used, causes some apps to try and resend it without adding more data). It doesn't seem to be a major issue, and is probably something to look into later after 1.0. I'm not sure if it's because the small data chunks should be buffered, or if an error isn't being properly propagated back to the app.
