Hmm, you access Blah.data after your 'SLEPT' loop finished. In this 
special case, it seems save, but it reminded me on one of 
Linus' "special" phrases: "Yes, it's manly, but let's face it, so is 
bungee-jumping with the cord tied to your testicles."

Okay, might be a bit exaggerated for this case..

Anyway, you should turn your code to use new style signals/slots. Raises 
readability and greatly reduces strokes. BTW, I tend to use lambda 
expressions instead of partials, but that's more of a personal
