Sadly, as I discovered today, we have code internally that expects to  
be able to set up some
joins and wheres ahead of time and still have them apply to an unlimit 

This code is using Jifty::Collection::implicit_clauses and when they  
don't get added, we get
way more results than we expect (mostly problems with trying to do  
acl'ing in the DB and limit what
we get back).

I'm not sure if we need to include the implicit stuff separately from  
the explicit limit() calls because
I agree that


should return all the rows, but should also let us do some magic
