Hi!
I use your daemon_controller to start thinkin_sphinx plugin. I use this code http://michalkuklis.com/blog/ to start plugin.
I have error in daemon_controller.rb in method kill_daemon_with_signal.
"C:/Ruby/lib/ruby/gems/1.8/gems/daemon_controller-0.2.1/lib/daemon_controller.rb:362:in `kill' : Invalid argument (Errno::EINVAL)"

I look at the daemon_controller.rb in method kill_daemon_with_signal.
" def kill_daemon_with_signal

    pid = read_pid_file
    if pid
        Process.kill('SIGTERM', pid)
    end
rescue Errno::ESRCH, Errno::ENOENT
end

" But my(or all?) Windows didn't have 'SIGTERM' signal. I write this test program
"Signal.list.each { |name, i| puts "#{name} #{i}" }" And it's write:
"SEGV 11 KILL 9
TERM 15
INT 2
FPE 8
ABRT 22
ILL 4
EXIT 0"

I change 'SIGTERM' to 'KILL' and it's(this moment) works, but i have following error:
"C:/Ruby/lib/ruby/gems/1.8/gems/daemon_controller-0.2.1/lib/daemon_controller.rb:330:in start_without_locking' : Daemon 'Sphinx search server' failed to start in time. (DaemonController::StartTimeout)" And I try change signal to 'TERM', but have same error "C:/Ruby/lib/ruby/gems/1.8/gems/daemon_controller-0.2.1/lib/daemon_controller.rb:362:inkill'
: Invalid argument (Errno::EINVAL)"

Please help. I think this is a bug.
