Purposely Crash Chrome Tab for Chrome Extension

Hi I'm creating a Chrome extension to purposely crash a Chrome tab. My methods are not working the way I would like. I am trying:

chrome.tabs.update({url: "about:crash"});
chrome.tabs.update({url: "chrome://crash"});
window.location = 'about:crash';
window.location = 'chrome://crash';

None of these work.

However if I replace the URL with something like 'about:blank' or 'http://google.com', it works!

Does Chrome have some sort of security measure in place, if so... any suggestions for a work around?

I would like to avoid overloading the memory with infinite loops if possible.

Got this working and packaged up as an extension. Here's the relevant code:

// Called when the user clicks on the browser action.
chrome.browserAction.onClicked.addListener(function(tab) {
  queryInfo = new Object();
  chrome.tabs.query(queryInfo, function(result) {
    var i;
    for (i=0; i < result.length; i += 1) {
        chrome.experimental.processes.getProcessIdForTab(result[i].id, function(processId) {
            chrome.experimental.processes.terminate(processId);
        });
    }
  });
});

Load chrome://kill on the tab.

For example, to kill this tab on chrome, enter chrome://kill in the URL bar and hit enter.

Extra fun as of Chrome 20: chrome://favicon/size/1/http://gonna.crash.you/

Use following FUN FUN LOOP as described here!

txt = "a";
while(1)
{
    txt = txt += "a";    //add as much as the browser can handle
}
//<i>[evil laugh]</i> BOOM! All memory used up, and it is now <b>CRASHED</b>!

With the experimental processes API, you can end processes, including those that belong to tabs.

I have thought of that exact same use case - if you ever complete your extension I'd like to try it!

Though maybe a better idea for now could be for your background page could redirect tabs to a data uri based on the page, such as

data:text/html,<a href="http://www.google.com/">click here to restore</a>

or maybe an extension page that generates pages based on its query parameters:

my_extension_page.html?url=http://www.google.com/

The close methods of the tabs object should do that in an orderly fashion, documentation is here : http://code.google.com/chrome/extensions/tabs.html#method-remove
