NSFileHandle fileHandleForUpdatingAtPath never returns

When another application has a device file open and I try to use NSFileHandle fileHandleForUpdatingAtPath to open the same device file, the call just seems to hang and never return. The API documentation doesn't say what should happen in this case. Does anyone know why it isn't returning?
