port search

[Randall Wood]

I think all the GUIs cache most of the port data if only because they  
need to display it and display different views of it rapidly. There  
is no use for having the port command allocate something on the order  
of 5 megs of RAM and walk the tree just to run a faster search. The  
GUIs have the luxury of long training - users kind of expect it to  
take a little longer to start before running fast, while CLIs need to  
be fast and lean.
