When using stdout/stderr it is no longer necessary to explicitly close the streams for the program to terminate. The automatic close is handled by always closing the associated receive port for write only streams when not waiting for any events. If a close or error handler is installed for stdout/stderr these will still keep the program alive. For stdin better handling of the difference between sockets and pipes have been immplemented. As a special case for stdin when reading from a terminal the a POLLIN signal with 0 available bytes is treated as end-of-file. This will trigger when pressing ctrl-d in a terminal as POLLHUP is not set in that situation.
