----------------------------------------
On Ubuntu, the test also passed, but I had an identical cleanup hang waiting to
get a connection during shutdown:

> Test needed for MySQL that exercises hopcount filtering during a load test
> --------------------------------------------------------------------------
>
> Key: CONNECTORS-496
> URL: https://issues.apache.org/jira/browse/CONNECTORS-496
> Project: ManifoldCF
> Issue Type: Test
> Components: Framework core
> Affects Versions: ManifoldCF 0.6
> Reporter: Karl Wright
> Assignee: Karl Wright
> Fix For: ManifoldCF 0.7
>
>
> User reports that ManifoldCF web crawls run on MySQL fail to find the correct
> number of documents, compared to web crawls run on PostgreSQL. The documents
> included differ from run to run. We need a test that duplicates the
> appropriate environment. >12000 documents, hop-count filtering enabled.
> > - Max Hop on Links: 15
> > - Max Hop on Redirects: 10
> > - Include only hosts matching seeds: Checked
> > - org.apache.manifoldcf.crawler.threads: 50
> > - org.apache.manifoldcf.database.maxhandles: 100
