ZEC took the route of disabling this by default, so debug.log files grow without limit,
in attempt to gather more data about CVE-2019-16930, which was fixed in the same emergency
release as changing this default behavior.
KMD has chosen to ignore that ZEC change, which I find reasonable. We take the middle path,
and 10X increase the size limit.
Now debug.log must hit 100MB to be resized, and potentially lose some data about attacks.
