I can see that being a serious concern for really small ISPs getting a /20
from a reserved /19 if they only currently utilize a /21 and have to fill
the /19 in 18 months.  We had 2 UUNet /20's to renumber out of.  Filling
the reserved /19 won't be a problem...I just need to file the paperwork to
get the top half of the /19 officially allocated.
