Is there a limitation for how much data you can send through an NSPipe?

No.

Or am I not using the NSPipe correctly?

Yes. BTW, you are also leaking 3 NSPipe objects.

Please help me out here; I've looked all over developer.apple.com, TIL and connect.apple.com but I can't find any report of a bug in the NSPipe definition...(?)

You'll need to read some documentation on unix pipes. They are finite in capacity, and if they "fill up", the writing task will block until the reader reads some data out and "makes room", then will continue writing. Since you are doing a [task waitUntilExit] once the pipe is full, you block forever.
