I'm not going to answer your question directly, other than to say that
Lucy::Store::RAMFolder wasn't really designed for production use, and so I don't
know if things like merging were ever considered. Whether is meets your needs is
probably a try-it-and-see thing.

I should note that the entire architecture is built around mmap so you're
getting the benefits of in-memory OS-level performance with persistence on disk.
So without digging more deeply into why you "might need to have the index
memory" if it is assumption about performance, you might not see much gain by
using RAMFolder.
