I know that you didn't add the `kill-buffer'.
I was wondering if the `mapcar' that gets invoked later might break
something, since the reference to the ` *mm*' buffer will be put into
the mime handle alist for future deletion, even though that buffer
gets killed here.
However, I just now figured out that this is probably not a problem,
since `mm-destroy-part' only does a `kill-buffer' if `buffer-live-p'
succeeds on the buffer referenced in this alist. Hence, in this case,
we're safe to do the `kill-buffer' on the ` *mm*' buffer *and* to add
a reference to this killed buffer to the alist.
Now, as long as we're sure that no other code tries to do something to
this killed `* mm*' buffer in the alist prior to the `mapcar' call,
then we're OK.
