Is it ensured that insert and delete-operations within a file at
byte-granularity are possible with (or independent of) that key layout? I think
that, for this feature, it is required that the "offset" part of a key is not
an offset measured in filesystem blocks (4KB), but an offset measured at least
in byte-granularity. This limits the filesize to 16 ExaBytes. Still enough, I
think. :-)
