We often have two choices: (a) throw up our hands and exit, or (b) log a warning and push
through the issue, potentially losing data. I think some users are very sensitive to dataloss
and would prefer that the system become unavailable rather than continue with potentially
lost data. Other users just want the system to stay up, and if they lose a log segment it's
fine.
