Review Comment:
   the main reason bootstrap regression failed to be detected in burn test was 
that it switched to using the sync point's emptyTxn, which has 0 keys... since 
ListRead supports ranges it was able to return the data requested from 
bootstrap even though its inputs were outside of the range of `keys`... This 
check helps protect that from happening again.
