> We should implement hole punch coalescing in the log block manager. I'm not sure whether it'll be faster than per-block hole punching, but it should definitely be no worse than what we do today (and it will definitely reduce the number of syscalls).
> To do this we need awareness within the LBM of when we're deleting groups of blocks, which should come through KUDU-1943.
