How can I run a function on every page load?

I am testing a large app, and I want to check for certain conditions on EVERY page load. For example, make sure that the header is right, that there are no error messages shown, etc. I do not want to customize every recorded script for these common checks.

Is there some hook I can use to run a custom function on page load?

I've been messing with the source in concat.js and I did manage to hook in a call to my custom function, but that function (wrapped in <browser> tags) does not have access to calls like _log() and _fail(), so if I do detect a problem, I can't do anything about it. The code I added was to the bottom of Sahi.prototype.onWindowLoad:
if (typeof onPageLoad=="function") {
onPageLoad();
}

Any ideas? Is something like this already supported, but I just can't find it?

Okay, I got a solution working for my needs. Here is what I did:

1. In concat.js:
Sahi.prototype.onWindowLoad = function (e){
...
// Added by Matt to allow running function on every page load
if (typeof onPageLoad=="function") {
onPageLoad();
}
}

2. In common.sah (which I include in every test script):
<browser>
function onPageLoad() {
if(_exists(_div("error_message_display"))) {
_log(_getText(_div("error_message_display")),"failure");
_sahi.stopPlaying();
}
}
</browser>

It works!
Any thoughts?
