There's no such interface, no.

I've yet to see anyone present reasonable data that show there's a noticable
gain to be had by providing such an interface.

The little profiling I've done has rather showed that the amount of time spent
on copying data in a regular libcurl-based transfer is rather insignificant.
Of course it will depend on particular use cases and target architecture etc,
so I'm open to get proven wrong.
