You mean async crypto with 10 stacked devices? Find me a single
user who does that.

Traditionally stacking didn't work very 
well in the kernel due to the limited kernel stack overflows. 
I don't think that's significantly different here.

Anyways stacking could be probably fixed, but it's also that 99.999999%
of all dm-crypt users don't stack or use async but simply need a 
scalable dm-crypt.  Extreme stacking is extremly low on the 
priority list.

Right now dm-crypt seems to have other problems anyways that need
to be addressed first.
