However, is it acceptable to call a copied block from within a render callback?  Assuming the code within the block doesn't block the thread, allocate memory, call objective-c code or do any of the other "bad" things, is there anything inherent in the block calling mechanism itself that would preclude its use?

I don't believe so. A block invocation is just an indirect function call.
