While waiting for Adrian, I noticed with this comibination:

  Fset_input_interrupt_mode (Qt);
  (custom-set-variables '(display-hourglass nil))

then after doing `M-! sleep 1000' I can no longer quit with
C-g but to wait the child process to finish itself.

I doubt SIGIO really works on Cocoa GUI mode, even
input-interrupt-mode is set to t, SIGIO may not be properly
initialized, more work needs to be done.
