new dired viewer

[John Russell]

This isn't so much a bug report as a suggestion.  I just downloaded
emacs from cvs yesterday.  I really like the dired viewer that allows
the spawning of external viewers for certain file types.  However, emacs
seems to have to wait for the process to die.  Is there any way to start
a viewer and then cut it loose?  It would be nice to view a pdf in xpdf
and still be able to use emacs afterward.  Thanks.
