I actually unset every possible var, and also checked the destructors 
with possible external ressources (mysql handles and query results).

It could be a circular ref left over.
But I searched for almost one year for such a beast and found nothing.
So I rather suspect it's php itself, which I didn't compile for memory 
tracing, yet.
