I ran the test 100 times on linux/x86_64 with no failures.
Wondering if it was a port selection problem (it is using the
doomed-to-intermittent-failure Support_PortManager), I ran 100 times in
parallel on two sessions on linux/x86.  I saw no failures.  If I'd have
stopped here I'd probably have been happy.  But a further 100 runs on
x86 on debian oldstable (etch) had one crash out of 100 runs with the
following stack trace:

Program terminated with signal 11, Segmentation fault.

This is unlikely to relate to the HARMONY-4116 issue.
