Here's an update on the version 4 WIP testing.
I pulled the SATA cable on the drive a bunch of times and forced HAMMER
to go into crash recovery and it seemed to do a good job.
I will probably implement the actual REDO as version 5. There's already
plenty in version 4 related to the UNDO FIFO changes to support faster
flushes and the later REDO to warrent its own version.
However, I want to do another weeks worth of testing for version 4
to be sure. Version 4 is still WIP and is not yet ready for prime
