All currently-supported platforms appear to have IPC capabilities in the default pipe. Would it be worth changing the default from PROP_NONBLOCK|PROP_BIDIRECTIONAL to PROP_NONBLOCK|PROP_BIDIRECTIONAL|PROP_IPC? That wouldn't break any current code, and would mean that simple calls to stdout->pipe() would be guaranteed to work (instead of just happening to work). ChrisA
