I wasn't sure how to hook up the DDB paging code to it, so didn't.  Or at 
least, I tried what seemed obvious (copy and paste from db_ps.c) and it 
didn't work for me.  If someone else would like to hook up the DDB pager, 
that would be great.

BTW, when I glanced at the DDB paging code, I noticed that &quit is passed 
into the setup routine, but didn't actually see a teardown.  This is 
probably because I didn't look very hard, but if it's actually the case 
that &quit is never unregistered, that might result in stack stomping...?
