The other upside of opening a database connection for every request is
that each connection (and therefore transaction) is short-lived, so you
have less opportunity to read in stale data and generate write
conflicts.

However, I think Nic (as I) was actually interested in finding out how
to run a ZEO setup that doesn't use an asyncore loop :-)

Take care,
