This would be really great for us. We currently stuff all our shared code
into one big 'catch-all' XL. Every time we want to add something new, which
we do a lot, 'cuz we're porting from CM, we have to kill everything that
uses the big mutha XL. This is a real problem for us, being in a downtime
intolerant environment.
 
With dependent libraries, we could just add a new XL which references the
others. If we need to fix something in an XL it would only require shutdown
of those facilities which are affected by the change.
 
When will this be available?
