Description

I saw that obdfilter-survey is taking between 1-2 hours to run in the current test configurations. However, there are no useful test results being generated from these test runs, so this is a complete waste of testing time.

It is still useful to run obdfilter-survey with a minimal set of parameters just to ensure that this script and the corresponding kernel code continues to function.

The current code should run a minimal set of tests with SLOW=no using

{ nobjhi=1; thrhi=4; }

, but since 2012-01-25 obdfilter-survey has been running for all review tests, which never happened previously, and taking 3000-5000s. It isn't clear why this is happening, but may possibly due to enabling SLOW tests on all review builds, and that obdfilter-survey was added into the review test list. Before changing anything in this test, I'd like to first understand why these tests started running, and under what conditions they are run (e.g. SLOW=no or SLOW=yes).
