---------------------------------------------------------------------
So [~benedict] I rebuilt 2.1.10 with a merge of your diagnostic patch plus the
changes you mention above for integer overflow. I tried this on a node where i
had re-enabled assertions. i THINK but i am not certain that the assertions
suppress seeing the commit log IndexOutOfBounds exception, i will confirm this.
but the GOOD news is that this version DOES seem to fix the startup problem! I
will confirm this on the next node that fails where assertions are off. By the
way, it seems like this may also be leading to sstable corruption (probably not
surprising since it's flushing sstables when the IOOB exception happens?)
