I know there are problems related to this with INTHREAD, but they aren't
very easy to solve and for now I've more important things to do.. If it
seemed to work before, it was due to luck or due to some bug causing an
unnecessary index rebuild. You could set :INDEX=MEMORY to work around
this, but I don't know how much worse the performance would become. Or
you could just manually delete the virtual indexes once a week.
