Hi, I'm more proficient at Perl than c, so I made a Perl version of
your problem, and received a good answer.

See muppet's reply to:
http://mail.gnome.org/archives/gtk-perl-list/2008-December/msg00036.html

Basically, your timer won't be added to the event_loop until the 
button callback returns. There are some hacks around it, like putting
a do_one_loop in your for loop.
