I don't recall what the intent was here. Can't believe that it's been
almost 5 years since I wrote this. I wish I had left a few more
comments in the code for me to go on.

Obviously the continue should be removed since it's not doing
anything. I don't believe that we'd want a continue statement in
there to get outer loop. That would change the current cmm_page_array
pointer (pa_curr) to the next in the list after it may have just been
reassigned to pa_last->next.

It may be the case that an earlier version of the code had statements
in the inner loop after that continue that I wanted to skip, or I just
did something silly.
