Hi,

The gtk-devel mailing list is mostly for development of GLib/Gtk+

- does your read_request() callback return TRUE whenever called? (or
rather: make sure it returns something in the first place)

- you should probably also watch for G_IO_HUP and G_IO_ERROR

- there are a bunch of libraries that provide higher-level abstractions
for this stuff based on GLib, such as GNet or libgnetwork (just FYI,
there's nothing wrong in principle with doing things directly).
