The exception is cache_views, which in D5 does not rebuild-on-demand but only on certain events, such as adding a module or clicking the "clear views cache" button on the Tools tab of the Views admin page. Don't clear that one manually unless you really know what you're doing. :-)
I'm not positive on this, but from what I can tell, the views cache isn't a special case, and using that tool simply empties out the table like any other cache clearing operation (via cache_clear_all).
