These options don't seem very good to me in a general purpose API.

We can't assume that our client used malloc. They might have used new, mmap, objc_createInstance, or a custom allocator.

Requiring a valid pointer for the lifetime of the VM is a difficult model to program with. For example, we couldn't use that model in the browser, or in the audio processing context being discussed on webkit-dev.

This seems more reasonable to me.

It would be nice if we didn't have to reinvent a generic API for "referenced counted data pointer". Perhaps we can write this API in terms of CFMutableDataRef and NSMutableData.
