mysqltest: Result content mismatch
.......

Please ignore the warnings. They must be handled within
another bug report.
A pure "show processlist;" without preceeding
   --replace_column ......
must produce lead to unstable results depending
on
- the amount of preceding tests
  (-> column Id)
- the current performance of the testing box
  (-> column Time)

MySQL 5.1 and 6.0 have the same weak test.

How to repeat:
Either
- run this test
  ./mysql-test-run --big variables-big
or 
- just read the script and imagine what could happen.

Ok to push when you have dealt with the truncation warnings that Patrick mentioned. I get the same result as him on my desktop.
