- There is a whole lineage of palces that could deliver coprrupt data over
- and beyond RMS's global buffers. The whole I/O subsystem, including caching
- products are just as risky.

- Your idea of RMS Global buffers and a possible corruption is much like the I/O
- subsystem writing a block of data to the wrong LBN. It is possible, highly
- unkikely as has been proven over time.
