Essentially, I'd like try_realloc to succeed whenever it can succeed
with less work than free + malloc. With the current implementation, that
is when the current block can be grown in place, and when it can be
grown via remap.

For std::vector, it would be beneficial to have an interface which succeeds only if the address doesn't change. I think this would fit your needs as well.
