... BTW, in situations in which you don't know which objects to deactivate, an alternative is to call cacheGC on the connection frequently. This is fairly inexpensive and incremental.
But, it can kill volatile variables as well -- which may lead to trouble, until we have implemented something like "Garanteed lifetime for volatile variables".
I've got no problem with the current behavior of volatiles, I understand how they work. But personally I've not been able to successfully write walk code against very large databases that doesn't consume RAM without bound using only cacheGC. If I write the same type of code using _p_deactivate against each object I walk, I can keep memory under some sort of control. - C
