When running unit tests for the whole TWikiSuite.pm, my tests crash with a memory fault after the process has grown to some 130MB.

That's the same thing as Item2158, only that the cure needs to be applied to most test suites:

Many unit tests create a TWiki->new() during their set_up routine, i.e. repeatedly for each test. But we know since Item2158 that TWiki objects contain circular references, so they need to be properly destroyed.

The easiest way would be to call $twiki->finish() during the tear_down() routine in all those packages which create the object during set_up().

Aaargh. Many test cases create new TWiki objects on the fly, or TWiki->new(). I give up after having reduced RAM to <100MB for TWikiSuite.pm on my machine, so I can run the suite. Feel free to investigate and provide further patches, otherwise I'll close the item in a week or so.
