I think it would still be better to make the change, along with the caller.  The only reason it was done that way originally was as an optimization step (the string never changes, so don't reformat the string multiple times: in each callback).

I'm wondering if it might even be better to use the _MULTITHREAD value and let SQLite decide, internally, when a mutex is warranted.

Of course, given that the API is marked experimental, it's difficult to justify the danger of that API disappearing unless we included the SQLite source directly.

These bugs have been tracked to the actual Berkeley code Asterisk uses, which is very very old and unmaintained. This patch replaces the Berkeley code with SQLite3 while maintaining exactly the same API. If there is no sqlite3 version of the database already and there is a Berkeley DB version, it automatically converts the old database to the new format.
