Re: Stdio.File()->notify

Its about time it gets into stable pike releases, considering that
inotify was added to the linux kernel in 2005.

I am not sure how the notify() API is supposed to be used. I think it
never really got finished. Anyway, as it currently exists, its not
usable. Even when setting up the signal handler correctly, I don't see a
way to decide which file object actually corresponds to the file
descriptor which triggered the event.
