Understood. But how difficult would it be to start a subprocess from the build
just prior to starting a test, and have it monitor the test and kill it if it
takes too long?
(See the section "Killing a hung test" at
http://wiki.apache.org/lucene-hadoop/HudsonBuildServer )
Once the test has been killed or if the test exits normally, the subprocess
would just exit. The task that could do this is a pretty simple piece of
shell-scripting.
When I have killed just the process running the test manually, the build
resumes.
If we did this, I don't think we'd need a timeout on the whole build, because
the reason builds take a long time is due to a hung test.

I wasn't really suggesting killing the whole build. In my experience just doing
a kill -9 on the stuck test kills the test, and the build just resumes.
