Yes. But, also one that supports pinging the database and creating a
new handle if the connection is dropped.

DBI->connect_cached should, but I assume what's happening is RDBO is
issuing a disconnect forcing a new handle to be created.

No, I don't think that's it. What if the $dbh connection is lost?
DBI->connect_cached will create a new connection in that case.
