#1304: fastcgi egg segfaults with SIGUSR1

 libfcgi has the option to gracefully terminate in response to SIGUSR1.

 The fastcgi egg doesn't properly detect this case and segfaults. When it's
 shutting down, the FCGX_Request's out field (and probably all the fields)
 go to null.

 This patch to fastcgi.scm fixes it:
 {{{
 245c245,246
 <       (and-let* (((callback
 ---
 >       (and-let* ((_ (fcgi-request-out req))
 >                  ((callback
 }}}

 The fastcgi egg is very old and the original author doesn't maintain it
 anymore. I would appreciate it if someone could apply this patch.
