HAMMER VFS - REDO implementation base code part 3/many (addendum2)
* I/O interlock required when flushing UNDOs because REDOs can now
be entered without holding the sync_lock.
* We have to cache the UNDO/REDO FIFO's next index before flushing
in case additional entries are created while we are finishing up
the flush.
