I'd like to use one NSPipe instance for multiple successive NSTasks.

Why?

I've tried this but can't get it to work:

[snip]

The second pair of setStandard methods cause an exception: "Exception raised during posting of notification. Ignored. exception: *** -[NSConcreteFileHandle fileDescriptor]: Bad file descriptor"

Can anyone point out my mistake?

Yes: wanting to reuse a pipe for successive tasks. The sub-task will close the pipe and then it is gone (that is why the file-descriptor is "bad").
