Maybe we could dream up a `Monster`/`Nightly` unit test that randomly gets big merges going (index from `LineFileDocs` -- nightly get a a biggish corpus), then randomly `IW.rollback()`, then counts how many nanoseconds / bytes (`LongAdder` tracking how many bytes the various threads are writing in total) it took before `rollback()` finished. It's sort of like measuring stopping distance for a race car going 300 kph. Not sure how the test could binarize (pass/fail) that reliably but we could start with that test and run it for a long time and see if there are surprises... -- This is an automated message from the Apache Git Service.
