launch many daemons from script/xxx

Hello, I try to launch many daemons from a script written in the
script/repository.

One daemon is launched per site (AR model "Site").
I want to load Rails environment just once.

Each time a daemon is launched, script exits.
I tried to "encapsulate" daemon launching in threads, but I have the
same issue.

Have you any idea how to do what I want to ?

my codes :

without threading :

(...)
Site.all.each{|site|
        p "start #{site.name}..."
        Daemons.run("#{RAILS_ROOT}/app/daemons/proxy_client.rb",
options.merge({:app_name => "proxy_client_#
{site.id.to_s}", :ARGV =>[ARGV[0], '--', "SITE=#
{site.id.to_s}"]})
}
(...)

With threading :
(...)
Site.all.each{|site|
        p "start #{site.name}..."
        @threads << Thread.new{Daemons.run("#{RAILS_ROOT}/app/daemons/
proxy_client.rb", options.merge({:app_name => "proxy_client_#
{site.id.to_s}",
                                               :ARGV =>[ARGV[0],
'--', "SITE=#{site.id.to_s}"]}))
                             }
      end
@threads.each{|t| t.join}
(...)

You can use Daemons.call instead of run.
