bug#1666: 23.0.60; Emacs goes in a malloc loop |

Following is the piece of Emacs Lisp code, which I tried to execute in
Emacs's *scratch* buffer to close all buffers except the buffer named
"buffer-name".
,----
| (dolist (buffer (buffer-list))
| (unless (string-match "buffer-name" (buffer buffer))
| (kill-buffer buffer)))
`----
Executing above Emacs Lisp code increases CPU usage and Emacs keeps on
allocating memory. This bug is reproducible always.
