Why is "bzr add" slow when "bzr status" is fast?

Hi,

I have a project that has a large number of files and directories. When
I run "bzr status" it reports almost instantly (which is great!) and it
lists the files that are unknown. These are the same files that should
get added with "bzr add" if no arguments are supplied - at least that is
my understanding. When I run "bzr add" though the CPU goes up to 100%
for a few seconds and then it adds the unknown files that were listed by
the status command.

Why can't it use the same code as status does to work out which files
are unknown and should be added?

Cheers,

Nick
