As noted in this announcement, I started writing some basic tutorials for D.

At a post a week, I've got 10 weeks of backlog posts. One of these is a post on input output piping.

I'm wondering if there are any thoughts for simplification. I don't mean simplify to perform the same end result, but is the threading and data copies as simple as they could be? Did I misrepresent anything?

Your approach is OK for more complicated cases. When you need to just pipe one process into another, create a `pipe`, pass the writeEnd to the first process's stderr, and the readEnd to the second process's stdin. To discard output, pass File("/dev/null", "w") to its stdout.

There is a ticket somewhere in Bugzilla to add something like Python's Popen.communicate to pipe multiple things at once. it is not difficult, on Linux it is a select loop, doesn't even require threads. There was no consensus on what the interface should look like.
