I do the same thing--good to hear from John that keeping it open is
OK.

But another question that this provokes, at least for me is:  what
happens when you call .connect() on the same database multiple times
from within different parts of the same app?  Is that bad?  And is it
that there now multiple connections to the database, or one connection
that has multiple names in different namespaces within the app?

I'm not even sure what a "connection" really is; I assumed it was
nothing more than a rule that says to write to the database with the
file named in the parentheses.

Further elaboration from the community would be helpful.

Thanks,
Che
