It doesn't make sense to use a connection pool for an in-memory SQLite3 
database.  Every time you connect to ":memory:", you get a brand new, 
empty database.

If you want this to work, you need to be able to establish multiple 
connections to the same database.  You could do that by making your own 
DB-API 2.0 module that wraps sqlite3 and always hands back the same 
:memory: connection when its connect function is called.
