Also, we could make it slightly cheaper yet, by changing the condition
to

            hctl->freeList[0].nentries > (long) (hctl->max_bucket)

ie drop the +1.  I'd argue that this is actually a more faithful
rendition of the previous condition, since what we had before was
basically

            hctl->freeList[0].nentries >= (long) (hctl->max_bucket + 1)
