I am writing a screen saver that forks a process and reads its stdout chunk by chunk. Since I didn't want it to block on reads, I tried to find the non-blocking IO parts of Cocoa. I found Cocoa's NSNotificationCenter, and the associated methods with the NSFileHandle class, and that seemed to fit the bill. It works fine *except* it doesn't notice the closes.
My guess is it has something to do with the main loop being blocked after the close. It notices the last chunk of data and the close at the same time, but then it never notices after my last waitForDataInBackgroundAndNotify call. I don't want the routine reading the data to be blocked, but I want to know in a timely way if the file handle is closed. How do I do that? What should I be doing?
