Implementing concurrent Test Cases in Ruby and Watir

Can anyone point me to an example of executing a test case in multiple
threads concurrently?

There are 10 instances of the application under tests running on 4
different boxes.

I am attempting to build a release night test that will use the url and
verify what instance of the web app we have accessed (by checking a
developer inserted tag in the source). If the instance of the app has
not been encountered a series of tests will be executed, other wise the
script will log off, close the browser, launch a new browser and try
again.

I would like this process to run from multiple threads concurrently in
hopes of hitting all app servers quicker.

This test has been simulated manually, but I am not sure how to
implement in Ruby and Watir.

Any suggestions would be greatly appreciated.

Look at SW Explorer Automation
(http://home.comcast.net/~furmana/SWIEAutomation.htm). The program
creates automation API for any Web application based on HTML and DHTML
The API is used to visually record the test scripts.

The number of test instances is limited only by Windows limitation on
number of IE instances.

Thanks Alex!

I will take a look at this when I get some down time.
