Hello. I'm testing Ruby XMLRPC support right now. All works fine,
except XMLRPC::Server#shutdown :( If i run following ruby 1.9.3 test
code, it fails to shutdown server on both Windows 7 and OSX 10.7:

# server.rb

require "xmlrpc/server"
require 'thread'
Thread.new { sleep 10; $server.shutdown() }
$server = XMLRPC::Server.new( 1234 )
$server.add_handler( "test" ) { true }
$server.serve()

# client.rb

require "xmlrpc/client"
server = XMLRPC::Client.new( "localhost", "/", 1234 )
loop { server.call( "test" ); sleep 0.1 }

After 10 seconds the server writes "INFO  going to shutdown ..." to
stdout, but don't actually shut down and continues to handle incoming
requests :(. What i'm doing wrong?
