ps.test has the potential to harm succeeding tests
when there is a parallel high CPU load on the testing
box (run a compile or tests on other source trees...).
The succeeding test might process the result of
   SELECT ... information_schema.processlist
very early and see connections caused by ps.test
where the disconnect is not finished.

ps.test failed one time when I applied my non official
high load stability test.

My release was a mysql-5.5-bugteam revno: 3170
2010-12-07 but I assume ps.test in many other MySQL
versions have the same weakness.

How to repeat:
Not available

Suggested fix:
Take care that any disconnect ... is finished before
the ps.test ends.
