I thought that 'StreamOut Error' is a message from mod_python which is just printed to stderr. But then there's the post from Matt/Geoff suggesting this is an OS problem. The servlet doesn't notice any exception or error. It continues serving until it has finishedLongThing even if the user's browser stopped receiving the output long before ... sleep() will be called afterwards, but then the (useless) work already has been done. This is especially a problem because a user may do several cancels and reloads ...
