Oops sorry, this should be one of those only XEmacs functions:

,---------- Function: kill-buffer-safe ----------
| `kill-buffer-safe' is a Lisp function
|   -- loaded from "tinylibm"
| (kill-buffer-safe BUFFER)
| 
| Documentation:
| Do `kill-buffer' only if BUFFER exists. Does not signal any error.
| Return:
|   t             killed
|   nil           no such buffer
`--------------------

`kill-buffer' should do the trick, and should exist in Emacs, I cannot
corroborate that at the moment, though.
