funny results with 'port list inactive'

Hello,

I was in the process of upgrading my ports collection, when I've noticed that:
$ port list inactive | wc -l 
  3481
$ port list | wc -l
  3481

Is this to be expected?  Knowing that I have no inactive ports I would
prefer to have output similar to the one given by 'port outdated'.

Also I seem to have quite a funny timings with different commands:
time for 'port list':
	real    0m0.795s
	user    0m0.538s
	sys     0m0.100s

time for  'port list all'
	real    8m15.081s
	user    7m48.300s
	sys     0m17.354s

time for 'port list | sort' (which seems to return the same list as
'port list all'):
	real    0m0.843s
	user    0m0.537s
	sys     0m0.135s

Would anyone care to comment, explain?  My version of Darw^H^H^H^H MacPorts is 1.320.

All the best,
