use Glib::IO->add_watch to watch a file descriptor for input in the main loop:
http://gtk2-perl.sourceforge.net/doc/pod/Glib/MainLoop.html#integer_Glib_IO_add_

here's the GLib function that this wraps:
http://developer.gnome.org/doc/API/2.0/glib/glib-IO-Channels.html#g-io-add-watch

and a Gtk2::Helper method exists to make that easier to use:
http://gtk2-perl.sourceforge.net/doc/pod/Gtk2/Helper.html


basically, the idea is that you have the main loop watch the file descriptor
for input, and tell the mainloop to call some function when there is input
available.


this is a frequently asked question, but doesn't seem to appear in the gtk
faq...  it's been asked before:
