Xinha.free is slower than is needed

[guest]

There is a great likelihood that the Xinha.free function could be improved if the function only attempted to set the property to null if the property was confirmed to start with an even handler such as 'on'. The patch below executes the collectGarbageForIE function in IE 7 about one quarter second faster for me (with a blank message body)

Xinha.free=function(obj,prop){
if(obj == 'javascript:void(0)'){return;}
else if(obj&&!prop){
for(var p in obj){
Xinha.free(obj,p);
}
}else if(obj && prop.indexOf("src")==-1 && prop.indexOf("inner")==-1){
try{
obj[prop]=null;
}
catch(x){}
}
};

Also, the flushEvent function has a series of iterating x++ bits of code that are not used anywhere within the function and add a tiny bit of processing time to the garbagecollect helper function.

* I don't see what's going on there in your code, why would obj ever be that exact string javascript:void(0), why are you skipping "inner" (assuming this is innerHTML, but it's not created a problem before) and apart from those two things I don't see a difference.
