FWIW in 6.2, we think this caused all of our machines to crash 12 hours after
making the setting.

[~reveller] If you fix this, please email users@ and tell everyone that we'll
change the HostDB to not sync to disk by default for 7.0.0. I don't know if
anyone will complain, but I really feel this is a much better default overall.

Yeah, either we should remove it, or we should fix it such that it's dynamic in
all cases (not just most cases).
