HI Jon & Oscar:

Just try to revert to 6087, and give it a test!

When bayesian filter marked one comment as spam, it will add two comment
records into db.

That's why I say the pipeline always run twice.

Take the defualt filters as example , there are 3 filters

1. NullFilter
2. CommentFilter
3. BayesianFilter

The $pipeline->process() will run these 3 filter one by one...

in 1st run:
NullFilter->CommentFilter->BayesianFilter(Failed), then it break.

in 2nd run:
NullFilter->CommentFilter->BayesianFilter(Failed), won't break .....

For the time being, we don't think this is a problem, becasue we just "HIDE"
it ...

Take the authimage "deleteFile" for example, I put @ in front of unlink and
ignore the error message, becasue we have no idea why filters run twice.

So, I just combine these two runs into one, and make sure each "filter" run
once. Why I can make sure ... Becasue I did not use "break" to break the
for-loop, I just let it go through all filters.

* If some filters fails, I just keep the first failed result into
* If no filters fails, I just keep the last filter result into

It is exactly the old way does.
