A very ancient copy of bdb I worked on once had a default page size
based on the filesystem on which it was created, and very large data
fields were implemented as a pointer to the actual data which was
stored in a series of linked pages. Hopefully they fixed the latter,
otherwise, seeking to random points in data is going to be expensive.
