Does that mean, that when an application thread is started a new connection is
established (in the case of Oracle with a olog() call), and when the thread is
about to finish the connection is closed (ologof())?
Is it possible to pre-start (similar to what Apache does when pre-forking child
processes) Zope application threads?
