Research direction

Start with the parallel for-loop APIs and their size_t handling, then investigate how TBB interacts with R's long vectors. Define whether long vectors can be processed correctly in parallel and identify the required changes before implementation.

Written by the indexing model from the issue text.

Description

I'm guessing TBB would be the limitation, but to be sure, would it be possible to process R's long vectors in parallel? Since the APIs use size_t in the parallel for-loop, I guess that would not be handled correctly.
