If you see a request come into ZServer, and you see the request go into
ZPublisher from ZServer, but ZPublisher never returns any data to ZServer,
that's an indication that something is wrong.  A SQL method hanging would
look like this, it's the same thing as any other Zope component hanging.

The "big-M" log is your friend, even in this case.  As a matter of fact,
it's *especially* your friend in this case because it will be patterned
against one or a few methods, which is an easy problem to track down.
