----------------------------------------------------------------
Here a patch that implements this annotation (@UseNoMemoryExpensiveCodec). I am
not so happy with it, as it also moves this codec selection shit into the
LuceneTestRunner). Maybe somebody has a better idea how to pass the flag down
to LTC. Unfortunately LTC creates the RandomCodecProvider per class not per
test method, so removing and readding the codecs from it is the only solution
to handle this per test method.
Mike, can you test if this fixes the problems. I had no time to check this, I
only implemented it.
