Surely the portindex is generated in one place (like where the svn  
working copy of dports is) and then this is synced to another place  
(the one where rsync syncs from). So even now there should never be a  
time when a user syncs and gets an incomplete portindex.

The only reason for the above ticket/commit is that I occasionally  
want to regenerate the portindex on my local machine, but during the  
minutes that takes to run, I might want to also do other things with  
MacPorts. Now I can.
