Subject: Threading best practices?

I am developing a small GUI application using jruby. It will be used
for testing API calls to my company's server. I would like my
application to execute server calls in a non-blocking way. In C++ I do
this by creating a worker thread that executes the call and then
invokes a postback to the main thread (similar to Java's InvokeLater).

How do I do this in Ruby?

My simplified code looks something like this:

def get_users
  Thread.new(server, successCallback, errorCallback) do |server, scb,
ecb|
    res = Net::HTTP.post_form(server, { "action" => "getUsers"})
    if res.body
      scb.call(res.body)  # => this should be wrapped in some sort of
InvokeLater ?
    else
      ecb.call("getUsers failed") # => this too
    end
  end
end

I would prefer to use the Ruby standard library over the Java library.

Eager to learn,
Francis
