Oh!
Thanks....
Sorry did not know about chromium-extensions.
Hello All,
I have the following problem:

Chrome's V8 Javascript engine is so fast I've never felt bad about
looping/polling for things. Go ahead!

I don't think we provide any guarantees about extension load order. You could file a feature request at http://new.crbug.com to have us implement an event that fires when all extensions are loaded.
For now, one thing you might try is to have each extension first register a listener for chrome.extension.onRequest, and also send a "ping" message to the other extension. One of the ping messages may or may not get lost, but once one of your listeners fires with a message from the other extension you know that both extensions are now up and running.

This is what I've done bellow...
Although the challenge is how to perform the loop without consuming 100$ CPU...
I solved this using the tabUpdate event... Maybe there is better method.
