You're not blind :) .

I didn't take care of which connection is used by which thread. IMHO, this 
belongs to another level, similarly to - for example - mysqldb vs. ZMySQLDA: 
the former just establishes a connection, the latter maintains a connection 
pool and takes care of binding a connection to a thread for the duration of a 
transaction.

For my code to be usable in Zope, it needs to be managed by a database adapter 
implementing such pooling & binding, plus lock releases on transaction 
boundaries.

In current state my code should fit the needs of code outside transaction 
management, such as zeo.memcache .
