Added a wait option to be used in combination with background:true

[mokkabonna]

This allows you to run several karma tasks in the same queue without getting multiple "port in use" warning.

https://travis-ci.org/mokkabonna/knockout.bindingHandlers.number#L2335

Also causes possible eventemitter memory leak warnings

https://travis-ci.org/mokkabonna/knockout.bindingHandlers.number#L2174

This would preferrably be implemented without needing it to run in the background. If karma supported being stopping without the whole process exiting then you could implement it like so:

server.start(data, function(code){
    server.stop();
    done(code === 0);
});

You would also get the benefit of getting the output from karma as it comes, not all at once like now with this wait option.

But until then I hope this is something you could want to merge.

If so let me know and I'll add the docs for the wait option as well.

Now you get the output as it comes.

Here is a build that uses the changes: https://travis-ci.org/mokkabonna/knockout.bindingHandlers.number/builds/10857212

Notice no warn errors as it spawns and waits each time. So we don't have several karma servers running.

Just what the doctor ordered. Thanks.

Is this something that could be considered? Been silent here. For instance the default setup for genrator-angular outputs

WARN [karma]: Port 9876 in use
WARN [karma]: Port 9877 in use

etc after each run, since it does that if you run grunt serve and triggers another karma server on watch.

Merged back from master to get the travis config, and it passes now.

@mokkabonna sorry for the long silence and thanks for your contribution.
If you are still interested here are a few things,

• Could you please add some documentation with example to the Readme for this.
• Could you please rebase onto the latests master.
• Change the commit message to follow http://karma-runner.github.io/0.12/dev/git-commit-msg.html

Thanks

Not really a priority for me anymore. Anyone else is welcome to continue the work.
