It looks like it acts upon whole chunks of memory, just like the
user _init function.  But after unsuccessfully trying to wind my way
through the UMA code for a few minutes, it's not totally clear to
me whether or not UMA_ZONE_ZINIT overrides the user _init function
entirely.  Maybe somebody who has used it will clear up the confusion.
