u could investigate is some custom login handler, eg I
think the pop before smtp is handled with some script - perhaps get that
to be some more complex script which implements the behaviour you desire?
I think this is an interesting area to improve - Good luck

More interestingly: for small sizes like 32GB, has anyone played with
the "compressed ram with backing store" thing in newer kernels (that I
