do you see the amount of data in the cache being all that much?
I haven't looked at your implementation, but for Ada, the cache is
updated when symbols are looked up, usually due to a user querying
something. So, I don't the cache to be all that big, and FWIW,
we have never even had to think of having a dynamic hash size.
