with open HANDLER Fixes a problem with schema.test visible using embedded server. The HANDLER was not closed which caused the test to hang. The problem was not visible if the test was run on a normal server as the the handler there was implicitly closed by DATABASE DDL statements doing Events::drop_schema_events().
