The test itself is not faulty. The testcase timeout problem happens if this IMHO mid size resource (space in vardir, virtual memory, amount of disk I/O) consuming test meets a weak (excessive disk I/O caused by parallel applications or paging) testing box. The modifications: - Move the most time and disk I/O consuming subtest for Bug 1820 into its own script (multi_update2) This will reduce the likelihood that we exceed the testcase timeout. - Replace error numbers with error names - Minor improvements of the formatting -
