The original scgi server module included a graceful restart mechanism.
I ripped it out because it seemed unreliable and complicated.  That, and
I have a deep rooted hatred of signals.  Having mod_scgi retry requests
proved simpler and more reliable.  However, on sites like LWN I can see
the need for a better graceful restart.

Your patch looks good.  I'd be happy to include it after it gets battle
tested.
