I think the problem (in particular) was that some callbacks were executed within a thread that was holding the stream lock. Since now all the error/timeout callbacks are delegated to the thread-pool, this should be fixed by definition ;-) (the thread-pool worker threads are not holding any additional locks, right?). That said, fell free to point out which part of the patch is working you! ;-) -- You are receiving this because you are subscribed to this thread.
