ECB uses this function in it's hook of
`semantic-after-toplevel-cache-change-hook' in the following way:
(or updated-cache
    (not (semantic-active-p)))

whereas updated-cache is the argument semantic-after-toplevel-cache-change-hook
Calles it's functions with.

This condition enables clearing out the method-buffer of ECB if the
Hook is called with a nil cache for a not-semantic-setup buffer.
==> semantic-active-p returns correctly nil for text-, tex- etc..
buffers. 

==> The question is to understand why 'semantic-after-toplevel-cache-change-hook'
Is called for not-semantic-buffers??!!

If i remember right, Eric, we have discussed a long time ago this point,
if this is a bug or a feature that these hooks are also called for
not-semantic-buffers with a nil cache. I can't remember exactly but
i believe you have removed this behavior for a while but after that you
have reactivated it again for some senseful reasons (which i can't 
remember)...but as already said, it's a long time ago... ;-)

Thoughts?
