[Issue 9735] [PATCH] try hard to find free space if database cannot grow

I wonder if this "try harder" approach is best activated via a flag on mdb_env_open? That way, only users who want the more aggressive search for free space get impacted.

I thought about it as well, but then I count'd find any use-case for the other (current) behavior. When the database can still grow, there is a clear trade-off between performance and occupied storage. But otherwise, should there be a trade-off between performance and (non-)functionality? Could you please think of an example where is it more desirable to return a failure than to continue trying hard (to find some free space)? Thank you!
