tree twice causes problems. So now MULTI-INDEX OR makes a copy of the
sub-expressions it uses to avoid code-generating them more than once.

function deletes that happen inside virtual-table destructors that are run
when a database connection is closing do not create new tombstones in the
function table after the function table has already been purged.
