Browsers hang when having multiple requests to jstestdriver server

[GoogleCodeExporter]

My question is how can I run different tests on the same tests machine, i.e. 
accessing browsers concurrently and not to need to restart browsers manually. 
Thank you in advance.

What steps will reproduce the problem?
1. JstestDriver server runs on remote machine.
2. Browsers are opened when the server starts and maintain always opened.
3. Different machines run same tests and access JsTestDriver machine at the 
same time.
3. Browsers hang, timeout occurs, and the project running tests don't compile 
due this error.

What is the expected output? What do you see instead?
The output is the infinite sequence of the following:
Microsoft Internet Explorer: {}
Microsoft Internet Explorer: {}
Microsoft Internet Explorer: {}
Microsoft Internet Explorer: {}
Microsoft Internet Explorer: {}
Microsoft Internet Explorer: {}
Microsoft Internet Explorer: {}

At this time we need to manually restart the jstestdriver server. :\

What version of the product are you using? On what operating system?
We are using jstestdriver1.3.2 on windows machine and maven plugin version 
1.3.2.5 to run tests.

Please provide any additional information below.

I am starting a server with the following parameters:
java -jar JsTestDriver-1.3.2.jar --port 9876 --browser 
"C:\Users\Administrator\AppData\Local\Google\Chrome\Application\chrome.exe","C:\
Program Files (x86)\Mozilla Firefox\firefox.exe","C:\Program Files 
(x86)\Internet Explorer\iexplore.exe","C:\Program Files (x86)\Mozilla Firefox 
3.6\firefox.exe"

I've experienced the same issue using IE9, it seems to often hang in the middle 
of the tests when an exception is thrown during a test, such as:

Error: Unexpected call to method or property access.

@daCrazyCoder, that is a different issue, which is currently resolved on head.
