Yes, ds-aa and -steens-aa were removed from poolalloc because we thought 
no one was using them, because we at Illinois weren't using them, and 
because nobody was maintaining them.  I believe one of our students also 
said they had become buggy.

A patch to update the web page would be nice; a patch to bring -ds-aa 
back to life would be even better.
