Well it's not quite as easy as Java but:
http://www.ruby-doc.org/stdlib/libdoc/monitor/rdoc/index.html


obj.methods.each do |meth|
    (class << obj; self; end).module_eval <<HERE
       def #{meth}(*args, &block)
           self.synchronize { super }
       end
HERE

end

obj.extend(MonitorMixin)

I did it in that order since I wouldn't want a synchronize  
{ synchronize }
