If mdb_stat fails (e.g. "mdb_stat db/ this_subdb_does_not_exist"), it exits immediately rather than abort the txn and close the env.

When another process has the mdb environment open while this happens, as long as it does not close it, no new transaction can be initiated. The whole env then effectively becomes read-only and unopenable for new processes.

A possible patch is at: ftp://ftp.openldap.org/incoming/Ondrej-Kuznik-20120824-ITS-7369.patch
