That's what I hoped when I sent my heap tuple header patches.
Actually this test catches a bug, which was in CVS from 2002-07-02
until 2002-07-30 and was not discovered during this time.  You have to
know, that I am a lazy person :-)  I wouldn't have written this test,
if the bug was found by one of the other tests.

You mean, that the test might fail on a system that takes more than
ten seconds to INSERT or UPDATE a single row?  I don't think this is a
real problem.  Should we change the timeout to 30 seconds?  60?  3600?
