At least on most UNIX-flavored OSes, "select()" and "poll()" - that
being what the GLib main loop uses, depending on what's available on the
OS - *always* say that a file can be read, so that won't help.
On most if not all UNIX-flavored OSes, you'd need to poll, just as "tail
-f" does (in an application using the GLib or GTK+ main loop, that'd be
done with a timeout, as suggested in another message). Some might, at
least in some versions, have other ways of notifying an application that
a file has changed.
