If notification comes by way of some sort of file handle, try using
an "input watcher" via gtk_input_add_full().

If not, could you check for the IRRC keypresses via a timeout instead of an
idle function?  That won't kill your CPU.

Or will keypresses be detected *only* when your code is explicitly
looking for them?  i.e. Will you drop events if you aren't constantly
checking.  If so, you have a problem...
