Hmm, not a fan, because the original lines of the event_trigger test,
which had no problem running in parallel, no longer do so.  Why not
split out only the new part of the test to run in non-parallel mode?
An effortless win of ~50 ms.

After this patch:

ok 211       + stats                                     644 ms
# parallel group (2 tests):  event_trigger oidjoins
ok 212       + oidjoins                                  103 ms
ok 213       + event_trigger                              57 ms
ok 214       - event_trigger_login                        16 ms
ok 215       - fast_default                               66 ms
ok 216       - tablespace                                156 ms
1..216
# All 216 tests passed.
