Marking this one to 'invalid' after reading Barry's comments. Makes

Title:
pbms.basic test failing randomly when run in rapid succession
Status in A Lightweight SQL Database for Cloud Infrastructure and Web
Applications:
Invalid
Bug description:
When you run the pbms.basic test in rapid succession (at least on my Natty
laptop), we are seeing random failures - looks like extra (not cleaned up?)
rows in the result set
Found this when attempting to repeat that random engine error failure we are
seeing in Jenkins slaves.
This only occurs when we're using shared mem (linking the test-runner
workdir to /dev/shm/...). Running with the --no-shm option is fine.
To repeat:
From the drizzle/tests directory:
./dbqp --suite=pbms --repeat=20
When failures occur, the output looks like this:
