Indeed it is.

I've removed it, and then decided to put it back since the definition of the hashtable isn't fully cooked yet, and I didn't want to miss this initialization point if it turn out we need to initialize that hashtable afterall.

I will remove it once the hashtable definitions are clear.

The rest of the review comments will be addressed.

Thanks!
