Without this, you can silently lose the ability to receive IPv4
connections if you stop and restart the daemon.

I've always wanted to ask HPA and Linus about this why we did
not do SO_REUSEADDR.  I've seen some non-git servers also not
using it, giving me an excuse to take a coffee break during work
;-).  Is it because they predate REUSEADDR, or is there a valid
reason to avoid using REUSEADDR under certain conditions?
