What do you think about  marking jtreg tests with higher memory requirements with a jtreg key like highmemusage  ? This way we do not need to put these tests into the _exclusiveAccess.dirs_  group, but get a way (only if needed) to execute those with high memory usage separately e.g. with lower concurrency.
