Because GTK is going to block in poll() waiting for events from the X
server, and if you block in a different poll() the GUI will lock
up. g_io_add_watch() adds a file descriptor to the existing poll(),
so you only have one poll() and nothing locks up.

i.e. you want to have a single main loop that runs always, rather than
switching back and forth between two main loops and locking up the
other main loop in between.
