That's reversed.  The limitation is that if you take a CGImage from an

Bah - yes. (In my rush to find the reference, I reversed the situation.)

Specifically, what Troy said was:

"When using -[NSBitmapImageRep CGImage], it's vitally important to keep the NSBItmapImageRep around for as long as the CGImage is in use. If you fix that problem, your crashes should disappear."
