Use `loc=auto` in SQLite3 filename schema like `file:foo.db?loc=auto`. Use `loc=auto` in SQLite3 filename schema like `file:foo.db?loc=auto`.
* Can I use this in multiple routines concurrently?
Yes for readonly. But, No for writable. See [#50](https://github.com/mattn/go-sqlite3/issues/50), [#51](https://github.com/mattn/go-sqlite3/issues/51), [#209](https://github.com/mattn/go-sqlite3/issues/209).
* Why is it racy if I use a `sql.Open("sqlite3", ":memory:")` database?
Each connection to :memory: opens a brand new in-memory sql database, so if
the stdlib's sql engine happens to open another connection and you've only
specified ":memory:", that connection will see a brand new database. A
workaround is to use "file::memory:?mode=memory&cache=shared". Every
connection to this string will point to the same in-memory database. See
[#204](https://github.com/mattn/go-sqlite3/issues/204) for more info.
