I was able to plug most of the memory leakage by adding this.context.clear(); to AbstractBridgedXWikiComponentTestCase#tearDown()
core/xwiki-core/ will test with argLine>-Xmx64m added and forkMode>pertest removed. On the one hand it would be nicer to route out the leakage but it also is nice to allow developers to use the context promiscuously in tests without worry about introducing stubborn leaks. I see a doubling in the speed of testing core/xwiki-core/ with mvn clean test. I'm not around much lately as there is a lot to be done to prepare for winter.
