Are you making the classic NSTask mistake of doing [pipe fileHandleForReading] or [pipe fileHandleForWriting] and then using that with -setStandardOutput: or -setStandardInput:? NSTask is odd in this respect, in that you're supposed to just pass the *NSPipe*, not a file handle derived from it. If you do the latter, IIRC (from the last time I did this, which was ages ago) it may indeed leak file descriptors. You only need an NSFileHandle where your process is going to actually read or write; they aren't used for passing pipe handles to subprocesses.
