Ultimately it's redundant work. I.e., every restriction you place inside the 
code still requires documentation, otherwise all you've done is changed "why 
doesn't this work" into "why doesn't LMDB let me do what I tried to do?" 
Simpler to only write the doc and leave the code pristine.

The library's purpose is to perform its intended uses efficiently. Misuses are 
not our responsibility. Preventing misuse is the responsibility of the 
documentation, it doesn't belong in the code.
