:-) Does that mean: "Uh, that's bad, but that guy's right - let's do 
something about it", or "Yeah, yeah, we all know, but nobody has enough 
time and motivation to fix this"?

Yes, this seems to work fairly well, with no leakage at all and minor 
speed impact.
In programs where the proper precautions are taken to avoid unnecessary 
copies, disabling the reference counting should not have a significant 
impact on the performance, right?


Cheers,
