There was a problem hiding this comment.
Shouldn't it always close pdbCopy before deleting it, not just on failure?

@promag I ran bitcoind through Instruments on a mac, and noticed I think 40k leaks (not 40 kb, 40 thousand occurrences..) on startup. One of the traces for leaked memory was the DB open call. |

If `DB->open()` fails, the `DB->close()` method must be called to discard the DB handle.
