if they'll be transmitted back to back, microburst style, like IP fragments are,
then 2. if there's implementation guidance to send the frags isochronously on
a schedule of some kind, to give other transmissions an opportunity to enter,
then 3. on today-typical MTU 1500 networks, "3" allows a today-typical 4K page
to be sent as a fragmented UDP datagram. in future networks we should expect
this ratio from then-typical MTU to then-typical page size to be more or less
similar.
