Older versions of mythfilldatabase used a huge amount of memory. If you
have a 4GB machine it could be swapping extensively. I have a script
that deals with that problem by splitting the run into separate pieces,
a few days at a time instead of the full 14 days in one load. The change
to fix this was made in February 2020. fixes/31 and later do not have
this problem.
