We did use that for awhile and it helps wwith the problem, however it has
some bad security consequences (someone else on the machine can also bind
to the port and steal the traffic meant for Spread.) so it was removed in a
security audit last winter.

p.s. some daemons can use reuseaddr because they use a priveledged port (<
1024) so must run with root priviledges. Spread uses a high port and so any
user can bind to it.
