Sure, but if that's the case, you don't need to have a blocking open()
interface. Having inotify tell your application that a file
descriptor that had been opened for writing has been closed
(IN_CLOSE_WRITE) should be quite sufficient.


[JON PRESS] I don't get the connection between what I said and your
point about not needing blocking open() interface. If I ftp into a
Linux machine and GET an infected file, you want FTP to go right ahead
and read it and send it to me over the wire?
