Just a data point: I couldn't find a priority value that didn't peg my 
cpu.  Anyone have different results?  I'm probably doing something wrong.

I changed

Glib::Idle->add (sub { ... });

to

Glib::Idle->add (sub { ... }, 1, $priority);

Where $priority was one of (1, 100, 200, 250, 300, 1000);

I either got no GUI (widgets never drawn; priority too low: 1, 100), or 
a working GUI and a pegged cpu (everything else).

The cpu usage drops as soon as the main loop quits.
