For the record, andres re-educated me in irc about this. The cache is
now a thread local cache and is cleared on every new transaction. This
lead to a small cleanup of the transaction machinery.

This hopefully makes it possible to use sqlos in a ZEO like way with
multiple application servers using the same database.

Just don't keep references to SQLOS objects over transactions.
