nsIProcess.init()fails in the second execution.

Using nsIProcess ( https://developer.mozilla.org/en/Code_snippets/Running_applications#Using_nsIProcess )
It fails in the second execution of "Using nsIProcess." 

IE View Lite 1.3.3 ( https://addons.mozilla.org/ja/firefox/addon/1429 )
It fails in the second execution of "View This Page in IE" also.

1.Start Minefield with NEW profile.
2.Install IE View Lite 1.3.3 ( https://addons.mozilla.org/ja/firefox/addon/1429 )
3.Execute "View This Page in IE" in the context menu.
4.Yoou confirm that IE executed.
5.Kill IE.
6.Execute "View This Page in IE" in the context menu AGAIN.

Actual Results:  
IE does not start. 

And you can see the following error message in error console.  
Error: Component returned failure code: 0xc1f30002 (NS_ERROR_ALREADY_INITIALIZED) [nsIProcess.init]
Source file: chrome://ieviewlite/content/ieview.js

Comment 1

[Alice0775 White]

The following code will fail in second time.
(Such a code is used by IE ViewLite.  )
// create an nsIProcess
var process = Components.classes["@mozilla.org/process/util;1"]
                        .getService(Components.interfaces.nsIProcess);
process.init(file);

In following codes, the second time is also successful. 
// create an nsIProcess
var process = Components.classes["@mozilla.org/process/util;1"]
                        .createInstance(Components.interfaces.nsIProcess);
process.init(file);


Therefore, It may be the cause that the extentension does not meet a newest syntax.

Comment 3

[Benjamin Smedberg]

This is by design, nsIProcess object cannot be reused any more.

Comment 4

[Michael Santoro]

In the comment 1 by Alice, the code makes reference to getService and createInstance.  I assume that these should both be createInstance.  Either way, I have tried both and have been unable to kill and re-run a process.
