Hi Arthur,

autoreleased "pipe"

since "pipe" is autoreleased "fh" is too.

>[fh readInBackgroundAndNotify]; // you are reading in

background, so your app will go through event loop.

When your callback is called, your pipe is probably
released and so your file handle is gone too, which
results in bad file descriptor. Get pipe with [[NSPipe
alloc] init] and release it when done with it.
