Instead of calling the mass indexer directly for all our classes, we
get the root indexed types and we index them one by one using the mass
indexer.

This is the only way to keep the number of database connections
sufficiently low for the constraints of a few customers of us with a
lot of entities and restrictions on the number of database connections
allowed.

At the moment, we just copied the toRootEntities code from the mass
indexer to do so.

See https://hibernate.atlassian.net/browse/HSEARCH-598 .

I'm not sure we agree it's something useful, do we?

Indeed.
