Ok, that is a start.
Thinking about this some more, i would like to have the ability to get
connections by name out of a pool of connections.
With using only one connection in an app i'm not able to detach another
functionality. Both are running in the same connection.
If i use a connection for every form, i can't run the same form twice.
So i think it would be useful to extend the current funcionality for the
use of a connection pool.
I'm thinking of something like:
getConnectionByName(self, connName, newcon=False)
to get either the one and only connection by this name, or get a new or
open connection from a pool.
To release the connection from the pool we could have:
releaseConnectionFromPool(self, con)
