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.

Before:

ok 211 + stats 603 ms
ok 212 - event_trigger 66 ms
ok 213 - oidjoins 113 ms
ok 214 - fast_default 71 ms
ok 215 - tablespace 161 ms
1..215
# All 215 tests passed.
