I had the same problem when I learnt about this and I created a page
over at EmacsWiki about it:

http://www.emacswiki.org/cgi-bin/wiki/FileNameCache

Nowadays I use `anything' and the `anything-c-source-file-cache'
source instead of my old iswitchb hack. I even have a special command
when I want to use `anything' just to get files from the cache (the
cache is so large that I don't want it to be used for normal
invocations of `anything'):

(defun anything-file-cache ()
  (interactive)
  (let ((anything-sources
         (list anything-c-source-file-cache)))
    (anything)))

Enjoy!
